Valve Description

The Powers #11 Water Mix Regulator is a self-actuating control valve which automatically maintains a mixture of hot and cold water at the desired set point without the use of external power.

Adjust the set point and the rugged self-operating #11 Regulator controls the mix of hot or cold water to maintain a constant temperature.

The instrument has a vapor pressure thermal system containing a thermally responsive fluid. This thermal system rapidly senses temperature changes at the bulb and accordingly positions the valve disc or plug, regulating hot and cold water flow to maintain the desired set point. The thermal system features a two-ply brass bellows with six reinforcing ribs on the bellows head and thick capillary tubing walls to insure long operating life.

Features

• Tight disc shutoff when either of the two inlet ports are closed

(up to 2")

• EPT disc is replaceable (on 3/4"- 2" valves).

• Lower guide stabilizes valve plug, assisting shutoff and modulation.

• EPT spring loaded V-ring packing provides good sealing and long life.

• A valve stem of highly polished corrosion resistant grade 316L stainless steel to decrease friction and reduce hysteresis.

• An adjusting nut mounted on ball bearings and a removable set point adjusting rod ease set point adjustments

• A set point reference scale aids temperature adjustment

Operation

The #11 Regulator should be installed with the hotter of the two liquids going into the bottom ‘B’ port and the cooler liquid going into the upper ‘U’ port.

(A)

When the temperature of the mixed liquid drops below the set point, the temperature of the thermally responsive fluid decreases, which decreases the vapor pressure in the bulb/ bellows. The force of the resulting vapor pressure is less than the spring force, so the bellows contract and the spring extends, which raises the valve plug up to decrease flow through the

upper ‘U’ port (cold) and increase flow through the bottom ‘B’ port (hot). This raises the temperature of the flow out of the common ‘C’ port toward the set point.

(B)

As the temperature increases toward or beyond the desired set point, the temperature of the thermally responsive fluid in the bulb increases, which causes the vapor pressure to increase.

This expands the bellows, compresses the spring, and moves the valve plug down to increase flow through the upper ‘U’ port

(cold) and decrease flow through the bottom ‘B’ port (hot). This lowers the temperature of the flow out of the common ‘C’ port toward the set point.

WARNING

In domestic water system, a safety shutdown device should be installed in conjunction with a #11 regulator.

Failure of the #11 thermal system will result in a constant rise in temperature (or constant high temperature ) of the fluid which you are trying to control.

Powers #11 Water Mix Regulators are typically used for automatic control of domestic or process water tempering. The self-actuated regulator can easily be installed in any convenient location.

Among its applications are: two-temperature hot water systems, jacket water cooling of engines or compressors, and many other industrial processes. Below are two typical applications.

The three-way regulator can also be used for bypass control, in lieu of a diverting valve, but it must be piped as a mixing valve, with two inlets and one outlet.

Sizing and Selection

Proper sizing of the Regulator is essential for correct system operation. An undersized Regulator will not allow sufficient flow at maximum load. An oversized Regulator may cycle and will not utilize the full valve stroke for efficient modulation of flow. This results in poor control and shortened valve life (quicker deterioration of valve disc and seat). For these reasons, the correct sizing of the Regulator for actual expected conditions is considered essential for good control.

Note:

Select temperature range (see page 14) with the set point in the upper third for best valve performance.

Size the #11 Regulator for actual rather than maximum conditions. DO NOT size according to pipe size; piping systems are designed for different criteria than process controls. Refer to

Powers document AE-1—“Valve Selection and Sizing”—for further recommendations.

Maximum Operating Pressure Differential (differential for fluid flow):

In order for the process medium to flow, a pressure drop must exist across the valve. “Pressure differential” is the difference in valve pressure between the inlet and outlet under flow conditions. The greater the differential, the greater the flow at any given plug position.

Though the regulator should be sized for actual conditions, you need to know the available differential at maximum flow. For optimum control, take as much differential as possible across the valve.

Refer to Maximum Water Capacities tables on page 4.

3

Maximum Water Capacities

!

CAUTION

Do not exceed maximum pressure differentials for given valve sizes. The maximum differential is the pressure the valve has against it at shutoff. Too large a differential can cause valve chatter and/or prevent shutoff.

Product Identification

A red label should be on the front face of the thermal system.

1. Product Label

Figure 1.

This label contains information required to properly maintain, service and order parts for this product. If there is no label, look for a white label on the inside of the thermal system legs (Figure 2A) or the valve body vertical yoke (Figure 2B). When replacing the original thermal assembly or valve body, secure the old red label onto the valve or thermal system or ink the number onto the body.

Position Valve

2. Select valve location with sufficient clearance to allow maintenance. Install valve in line. The direction of the arrows on the valve body must match the direction of the water or steam flow.

For best results, we recommend installing the valve in a horizontal line, and in the upright position with bellows head above valve. The valve may also be installed in any position within 90° of upright.

Testing the Thermal System

1. Stop the flow of fluid through the line.

2. Raise the temperature of the bulb above the set point temperature by placing it in a container of hot water. This will cause the plug to fully seat.

3. Figure 15. With the valve plug seated in the bottom port “B,” use a felt tip pen to mark the position of the packing gland assembly on the stem.

Distance between two marks = Valve Travel

15. Valve travel measurement

4. Place the bulb in a pan of cool water. Cool the bulb 30°F

(16°C) below set point so the valve is fully open.

5. With the valve plug now seated on the upper port “U,” use the pen to mark the new position of the packing gland assembly on the stem.

6. The distance between the marks is the valve plug travel.

This should correspond with the TRAVEL value in the VALVE

DIMENSIONS table on page 10.

No movement or only partial movement indicates the thermal system is defective and should be replaced with a new system.

Preventive Maintenance

Once every three months, inspect the Regulator as follows:

1. Visually check for leaks from the valve body joints, piping-tovalve connections, packing and stem areas.

2. Visually check for excessive corrosion on the regulator, including the bellows, capillary, bulb, thermal system legs, bridge, and yoke. Also check for excessive corrosion on the valve body.

3. Perform the instructions in

Testing the Thermal System

.

Less than full valve travel may indicate a leak in the bellows, capillary, or bulb, or other problems. This may result in excessive temperature in the process.

4. Test the temperature adjusting nut assembly for freedom of movement (see

Adjust Set Point

for instructions).

5. Remove bulb from the process fluid and check for excessive corrosion, or erosion that may weaken the bulb and/or cause thermal system failure.
