Pneumatic Actuators

PA / PAS Series

Pneumatic Double Rack and Pinion Actuators

Double Acting and Spring Return

(180 to 7000 in./lbs. Torque Output @ 80 psig)

Watts designed Series PA and PAS pneumatic actuators to meet end-user requirements. From the design stage, the concept of extended service life with virtually no maintenance has been paramount with maximum torque output per dollar and reduction of overall profile as key design considerations.

The double acting version (PA) and spring return version (PAS) fully comply with the original design concepts. The anodized aluminum body and end caps and die cast aluminum pistons protect against premature failure due to corrosion and provide superior wear resistance. Using special die casting methods, pistons are produced with maximum density and wear resistance at the gear tooth location.

Dynamic Seal

Static Seal

With special consideration toward safety, Watts revolutionizes rack and pinion actuator design with an internally loaded output shaft that cannot be removed. Additionally, PA units can be converted to PAS units simply by adding appropriate springs providing flexibility and simple inventories.

Acetal Bearing

All pinions are supported with non-metallic, non-corrosive, upper and lower bushings containing a dynamic seal. Dynamic pinion seals do not come in direct contact with the actuator body.

Extended life, contemporary design, safety, simplicity, and lower inventory levels combine to make Watts PA/PAS Series actuators the logical choice for quarter-turn pneumatic actuation requirements.

Modes of Operation

Double Acting PA

Air to Port “A”

Figure 1

Air is supplied to Port A, pressurizing the inside chamber, forcing the pistons outward resulting in a counter-clockwise rotation of the piston shaft. The air in the outside chambers is vented through Port B.

Air to Port “B”

Figure 2

Air is supplied to Port B, pressurizing the outside chambers, forcing the pistons inward resulting in a clockwise rotation of the piston shaft. The air in the inside chamber is vented through Port A.

Spring Return PAS

Air to Port “A”

Figure 3

Air is supplied to Port A, pressurizing the inside chamber, forcing the pistons outward, compressing the springs that are located in the outside chambers, resulting in a counter-clockwise rotation of the piston shaft. Any air that is in the outside chambers is vented through Port B.

Port “A”

No Air Pressure

Figure 4

With loss of air pressure to the actuator, the pistons are forced inward by the energy of the compressed springs, resulting in a clockwise rotation of the piston shaft. Any air that is in the inside chamber is vented through Port A.

Pneumatic Actuator Sizing Instructions

To select an actuator to meet the valve's operating conditions, the following can be used as a conservative method of selecting the appropriate actuator:

1: The minimum actuator operating air pressure must be established.

2: Valve operating torque at the flowing condition, (maximum valve operating torque can be used if flow details are not available).

3: The mode of operation must be determined to select a Double-Acting (PA Series) or Spring Return (PAS

Series) actuator. When the position of the valve in the failure mode is inconsequential to the application, a pneumatic double-acting actuator may be used. If there is a loss of air, the actuator will stay in its last position; except when valve dynamic torques exceed the frictional torque of the actuator pistons.

If the valve must return to a closed or open position with power or air failure, a Spring Return actuator must be selected. When there is a power or air failure, the springs will automatically return the actuator to the 0 (zero) position. Depending on how the actuator is mounted, the valve will travel either to the full open o r full closed position. Fail-open or fail-closed modes must be selected for air or electrical failures when using a solenoid.

4: Using the charts on page 7 and 8 of this manual, select the correct actuator for your application with the following method.

Example - PA

1 - Air Supply = 80 PSIG

2 - Valve Torque: 350 in/lbs.

3 - Mode of Operation = air double-acting (PA Series)

4 - Chart from page 7: @ 80 PSIG a PA-400 output is

400 in/lbs.

Example - PAS

1 - Air Supply = 60 PSIG

2 - Valve Torque: 380 in/lbs.

3 - Mode of Operation = spring return, fail closed (PAS Series)

4 - Chart from page 8: @ 60 PSIG a PAS-1500 output is 690 in/lbs. (See note below)

Example:

On a spring return unit there are several factors requiring review to ensure that the actuator torque will operate the valve in all conditions. Spring Return units have a lower output torque than the equivalent size in Double-Acting.

To size a spring return actuator correctly you must look at three numbers.

TORQUE DATA in/lbs @ supply pressure (PSIG)

First, identify which column you should be working in.

Since actuator air supply is

60 PSIG you should use the

60 PSIG and spring colums.

Start with the spring end which must be equal or slightly greater than the operating torque of the valve.

This is the torque that the actuator can put out at the end of the spring stroke. We can select a PAS-1500 with 10 springs, (410 in/lbs).

Next, move across to the 60 PSIG column to verify that the Air start is larger than the valve torque (690 in/lbs).

Confirm that the air end torque of the actuator will fully open the valve at the end of the air stroke (air end = 400 in/lbs).

The actuator has now been sized to ensure the valve requirements have been met.

PF Series Power-Flex Electric Actuator

Designed with the two most important electric actuator requirements in mind

— POWER and FLEXIBILITY.

At Watts, we pride ourselves on keeping up with the demands of the marketplace, and meeting those demands with innovative product development. The PF Series is no exception. With the

Power-Flex electric actuator, we have developed a versatile unit that packs the power required for your specific application.

This rugged electric actuator is designed to outlast and outperform similar designs. Our split phase, reversing motor, coupled with an efficient spur gear design, produces torques of

400, 700, 1100 and 2000 in./lbs., with a standard extended duty cycle motor. The unique combination NEMA IV, VII and IX enclosure is suitable for both weatherproof and hazardous environments - simultaneously. The heavy-duty male output shaft ensures positive valve cycling without fear of shaft fatigue over time. Additional features include a declutchable manual override, a highly visible position indicator beacon, and corrosion resistant epoxy coating - all examples of Watts’ continued philosophy of offering more features as standard at no extra cost.

The PF Series can be tailored to your application requirements by incorporating such options as: additional auxiliary SPDT limit switches, heater/thermostat, 0-1000 OHM feedback potentiometer, cycle length modules, 4-20 mA control board, and fail safe battery pack. Power voltages 115 VAC, 230 VAC, single phase,

12 and 24 VAC, 12 and 24 VDC.

PF Series Standard Design Features

ENCLOSURE

The PF Series electric actuator employs a unique enclosure design that meets NEMA IV Watertight and NEMA VII & IX Hazardous Environment standards, all within the same housing. The flange width is wider than a standard NEMA VII enclosure, incorporating an O-ring groove on the inside diameter, thus providing the capability for use in indoor and outdoor hazardous environment applications. A protective hybrid epoxy coating provides corrosion and ultraviolet light resistance.

SPUR GEAR DESIGN

The heavy duty spur gear design constructed of

4140 hardened steel far exceeds the life cycle capabilities of powdered metal or fiber gears.

The efficiency of this design allows for use of a smaller motor, resulting in less energy consumption.

Electro-Mechanical Brake

Available with AC voltage motors to prevent motor RUN-ON and maintains position of the valve disc on resilient seated butterfly valves.

POSITION INDICATOR

One of the features that received much attention to its design criteria was the method of valve position indication. After careful consideration of several different ideas, the agreed upon design was determined to be the best approach.

Unlike other methods employed by our competitors that require close proximity to the unit, this highly visible indicator allows for easy determination of valve position from greater distances.

13

PF Series Options and Controls

Additional Limit Switches

For position indication and/or interlocking other auxiliary equipment.

0-1000 OHM Potentiometer

Provides a resistance feedback proportional to the actuators position.

Heater and Thermostat

Maintains a constant 70°F temperature in cold climates and eliminates condensation in high humidity areas.

4-20 mA

Control Board

Watts 4-20 mA control boards are factory installed and available with the 115 VAC motor only. The 4-20 mA input provides modulating control for valves, dampers and other devices requiring accurate positioning control. In response to input command signal, the control board supplies electrical power to the motor driving the actuator in the direction necessary to bring the system into balance. Zero,

Range and Anti-Hunt adjustments are easily accessible for field adjustment. Direct acting or reverse acting modes, as well as, split range signals are optional.

Cycle Length Control Module

Can be factory installed for applications where fast opening or closing are not warranted. Cycle time can be field adjustable up to 10 minutes.

Failsafe

Electric

Actuators

Watts PF Series failsafe electric actuators feature rechargeable battery packs built into the actuator enclosure. Torque outputs of 400-2000 in./lbs. are available.

All optional voltages are available. A built-in trickle charger (automatic battery recharge) maintains battery life. The actuator is capable of 25 continuous cycles under full load without recharging batteries. The outside of the housing has a low battery charge indicator light. A remote local switch inside the housing facilitates start up an/or maintenance.

LVW Series Electric Actuators

Series LVW Electric Actuators are designed for rugged and reliable performance. Their modular, plug-in design simplifies actuator set-up and calibration. Upgrades and modifications can be done in the field in a matter of minutes, with no hard wiring, soldering or factory returns. The

LVW Series is designed to offer highly efficient operation in a compact package; from on-off duty, to modulating or proportional control.

Simplified Set-up

The LVW control board offers simplicity in setting up the actuator. With the Mode Selector Switch and the touch of a simple “enter, set and go” push button, the LVW Series

Control Board simplifies actuator set-up. On-board push buttons and slide switches make manual positioning easy and simplifies the selection of input signal type, feedback signal type and actuator fail position in the event of a loss of control signal. With a simple turn of a dial, signal sensitivity (dead band) and cycle time (speed) are easily adjusted.

Actuator shown with optional handwheel installed.

Standard Features At A Glance

• Electronics are simple to set-up and calibrate with a clearly labeled terminal strip and easy access to user wiring.

• Plug-in electronics for simple upgrades and modifications with coded connectors to make internal mis-wiring impossible.

• On AC Hot and AC Common connections, fuses will isolate damage to the Motor Board if power is misapplied, allowing for quick and easy repair.

• Auto-resetting .25 amp fuses protect limit switches and internal circuitry from overloads caused outside the actuator. They reset automatically, approximately 3 minutes after the overload condition is corrected.

• Standard 75% duty cycle at ambient temperatures up to 104°F.

• Visual position indicator is provided as part of the cover and clearly shows valve position.

• Dual conduit openings make wiring easier and keep power and control wiring separate.

• Limit switches provide end of travel control and position indication.

• Electro-mechanical motor brake is provided to prevent motor Run-On or hunting of valve.

• Manual override is declutchable and wrench operated for valve positioning when electricity is not available.

• Locked rotor stall protection stops the motor if excessive torque is encountered, providing protection from stall conditions (AC modulating applications only).

• Thermal overload breaker protects the motor from overheating for any reason and automatically shuts down until it cools and then resumes normal operation.

• Permanently lubricated, hardened steel spur gears throughout.

• Highly efficient, split-phase, capacitor run AC motors provide long life and high duty cycles with very low power consumption.

Notes:

1. The Current Draws stated include all options. If motor brake and/or heater & thermostat are not installed, the actual current draws will be less.

2. For DC models, Current Draws are provided at full running torque. If the actuator encounters an over-torque condition, such as a stall condition, the Current Draw will be vastly increased.

3. DC actuators have motors that do not generate heat, so they are not limited by duty cycle restraints. However, due to limited brush life of the motors, it is not recommended that the LVW series be used in applications that require continuous operation.

LVW Series Suggested Actuator Specification

115VAC and 230VAC Standard Electric Actuator

General

The quarter-turn electric actuator will comply with Part 15,

Class A of the FCC regulations for emissions and conducted radiation. It will also be certified by the Canadian

Standard Association (CSA) for weathertight or weathertight and hazardous locations. It will be composed of a compact cast aluminum housing, motor, gearing, limit switches controlled by metal cams for end of travel control, electro-mechanical motor brake, mechanical position indicator, and declutchable override as one complete unit.

Composite (non-metallic) housing covers are permitted for non-hazardous locations. All internal connections

(motor leads, limit switch leads, option connectors, etc.) will be coded, using different style connectors for each function to prevent mis-wiring. All connections will plug-in to simplify field repairs and upgrades. No preventive or periodic maintenance of any type will be required.

Motor

The motor will be capable of running continuously at full torque for up to 15 minutes at ambient temperatures at or below 104°F. Subsequently, the motor must be capable of

75% duty cycle. Motors will be split phase, capacitor driven with an auto reset thermal sensor and will provide high starting torque and be totally enclosed within the actuator housing cover.

Lubrication

All rotating power train components will be coated with a multi-purpose grease. Lubricants will be suitable for ambient conditions of -40°F to 150°F. For temperatures between 32°F and -40°F a heater and thermostat assembly should be provided.

Gearing

The powertrain will be comprised of hardened steel, machine cut spur gears. Stamped or cast gearing will not be allowed.

Manual Operation

A wrench-operated override shaft will be provided for manual operation. As an option, a metallic hand wheel may also be provided. The override device will be engaged through a declutching mechanism that separates the final output drive from the motor output.

Limit Switches

Actuators will have two standard end of travel switches, single pole double throw, rated at 10 amps at 115/230

VAC. The limit switches will be activated by metal cams mounted on the actuator drive shaft. At the end of travel, the power will be routed through the limit switches to a terminal strip location for pilot or position indication applications. The limit indicator outputs will be fuse protected with auto-resetting polyfuses with a working limit of 0.25

24 amps to protect the limit switches and internal circuitry from possible overloads originating outside the actuator.

To simply maintenance, these polyfuses will be permanent and do not need to be replaced. They reset automatically after the overload condition is corrected - in approximately 3 minutes. Two additional limit switches may be added to the actuator, adjustable to operate at any position, as required by the process application.

Open/Close Operation

Open/Close actuators will be controlled via two, powered, maintained contacts, one for driving in the clockwise direction and one for driving in the counter-clockwise direction. Power may be removed mid-stroke to position the valve. The AC input power will be fuse protected on both AC Hot and AC Common. The fuses will never blow in normal operation and will be conservatively rated and soldered in place for high reliability.

Proportional Control (Modulating Operation)

Modulating control actuators will accept a variable, proportional 4-20 mA or 0-10VDC valve position signal and respond by positioning the valve linearly with an accuracy of 1%. Normally, the actuator will drive clockwise in response to a decreasing control signal; however, the actuator will be capable of “reverse acting” operation

(driving counter-clockwise in response to a decreasing control signal) with no necessitated internal wiring changes. The actuator will also supply a 4-20 mA or 0-

10VDC position re-transmit signal, and provide the ability to adjust the cycle time of the actuator via motor pulsing.

A slide switch will enable the user to set the actuator response to a loss of control signal. Locked rotor protection will detect whenever the actuator is unable to achieve the position commanded by the control signal and will terminate power to the motor in order to prevent damage due to repeated stall conditions.
