Wetted parts

Hand held valves with internal air trigger

Hand held valve with electric switch

Hand held, wide ratio valves

Description

Aluminum wetted 2K-UL valves are lightweight and inexpensive, but have less chemical compatibility than stainless steel wetted valves.

The internal air trigger controls the air piston that operates the 2K-UL valve. A pilot port can be used to control a pump motor.

The switch signals the customer’s controller to open and close the ports on the 2K-UL valve using a remote 4-way air control valve which is not included.

The wide ratio 2K-UL valve has two features: a center inject nozzle in the nosepiece and a “shower head” tip. The features are helpful in applications when the mix ratio volume is greater than 10:1, specifically when minor volume is a lower viscosity than major volume.

Frequent cleaning intervals are required to maintain the center inject nozzle and shower head tip.

D

Accessories are available from your Graco representative. If you supply your own accessories, be sure they are adequately sized and pressure-rated to meet the system’s requirements.

D Fluid supply container: ground according to your local code.

D Flammable liquids in the dispense area: must be in approved, grounded containers. Do not store more than the quantity needed for one shift.

D All solvent pails used when flushing: ground according to local code. Use only metal pails, which are conductive. Do not place the pail on a non-conductive surface, such as paper or cardboard, which interrupts the grounding continuity.

WARNING

FIRE AND EXPLOSION HAZARD

To reduce the risk of fire, explosion, and serious injury, proper electrical grounding of every part of your system is essential. Read the warning section Fire and Explosion Hazard on page 5, and follow the grounding instructions below.

D

To maintain grounding continuity when flushing or relieving pressure, hold a metal part of the valve firmly to the side of a grounded metal pail, then trigger the valve.

How to Use the Valve Trigger Safety

WARNING


To prevent accidental triggering of the gun and reduce the risk of a serious injury, including fluid injection or splashing in the eyes or on the skin, lock the gun trigger safety when you stop dispensing.

The following grounding instructions are minimum requirements for a basic dispensing system. Your system may include other equipment or objects which must be grounded. Check your local electrical code for detailed grounding instructions for your area and type of equipment. Your system must be connected to a true-earth ground.

D

Pump: ground the pump by connecting ground wire and clamp as described in your separate pump instruction manual.

D Air compressors and hydraulic power supplies: ground the equipment according to the manufacturer’s recommendations.

D

Fluid hoses: use only grounded fluid hoses with a maximum of 500 feet (150 m) combined hose length to ensure grounding continuity. Check the electrical resistance of your fluid hoses at least once a week. If your hose does not have a tag on it which specifies the maximum electrical resistance, contact the hose supplier or manufacturer for the maximum electrical resistance limits, replace the hose immediately.

D

Dispensing valve: ground the valve by connecting it to a properly grounded fluid hose and pump.

System Setup

Fluid and Air Connections

1/4 npt(f) Fluid Inlets

There are three fluid inlets on the A-side and three fluid inlets on the B-side. The fluid inlets are located on the front, side, and back of the valve to permit various mounting and hose configurations.

1/8 npt(f) Air Inlets

The machine mount valves and the electric switch hand-held valves have an “open” port and “close” port, which are operated by a remote 4-way air control valve.

The air switch hand-held valves have a single air inlet.

This valve also has an internal 4-way spool which operates the air piston.

See Accessories , page 27, to order air control valves and tubing.

Inlet Check Valves

Inlet check valves are recommended on the fluid inlets where viscosity allows. An inlet check valve prevents back-flow or crossover when the mixer is plugged or one fluid is much lighter in viscosity than the other.

When required, a high crack pressure check valve is installed to maintain back-pressure on low viscosity fluids.

See Accessories , page 27, for a list of check valves.

Balancing the System

A proportioner is used to feed the two-component dispense valve. The system must be pressure balanced to avoid “lead-lag” ratio errors when starting and stopping the flow.

Balancing is done by hose sizing, inlet check restriction, and nose piece restrictors. A properly balanced system has near equal back-pressure on the gauges when flowing without a mixer installed.

The 2K-UL valve is supplied with 1/8 I.D. and 3/64 I.D.

restrictors (32 and 33) which can be installed in the nose piece to help balance the system. A special nose piece outlet that accepts a wide variety of restrictors with filter screens is available. See application kits manual 311230.

See Accessories , page 27, for a list of restrictive catalyst injectors.

Selecting Hoses

Hoses between your proportioner and the 2K-UL valve should be selected carefully. Many factors effect hose selection.

1.

Fluid Compatibility: Fluid must not degrade the core material or end fittings of the hose. Nylon or

PTFE cores are commonly used for chemical compatibility. If your fluid is moisture sensitive you should use PTFE or Moisture-Lok hoses.

2.

Pressure Rating: Be sure hoses have a working pressure rating above the pressure capability of the system.

3.

Compressibility: Hoses, especially nylon paint hoses, expand with an increase in pressure. A pressure change in the system may cause a volume change, which can appear as a ratio error with wide mix ratios. Compressible hoses absorb pressure spikes which is helpful to the operator during an application, such as trying to lay a bead.

4.

Internal Diameter: Small I.D.’s create higher back pressures, lower flows, and small retained volume. Typically hose I.D.’s are selected for: a.

System Pressure Balance. ”A” pressure drop vs. “B” pressure drop.

b.

Volume Balance. A:B volume ratio vs. Hose retained volume.

c.

Flexibility and weight for operator or robot.

d.

Overall Pressure Drop. Pressure drop should be minimum possible within the above guidelines.

5.

Length: Hoses normally are kept as short as practical to minimize pressure drop and compressible volume. 10 ft (3.1 m) is recommended for reciprocating pump systems.

System Start-up

When initially loading the fluids through the system, leave the mixer off until both fluids flow freely from the nose piece without any air. This prevents cross contamination from having fluid on one side pushing back up the other side.

309000 11

System Setup

Mixer Selection

Disposable mixers are available from 3/16 in. I.D. to

1/2 in. I.D. in lengths from 12 elements to 36 elements.

In general, wide viscosity or mix ratios require more mix elements. Small I.D. mixers produce lower flow, higher back-pressure, and waste little material. Large

I.D. mixers produce higher flow, lower back-pressure, and fewer lead-lag ratio errors. Different mixers can have differing “snuff-back” characteristics.

Setting the Amount of Snuff Back

The 2K-UL valve uses two “snuff back” restrictor rings

(13) to set the amount of snuff-back. These two rings are trapped between the main valve body and the nose piece. When the fluid valve pulls back to close, it enters the restrictions, stops flow, and pulls the fluid back until the needle reaches its carbide seat.

Maximum snuff-back results when both restrictors are used. Some snuff-back is still achieved without the restrictors because of the pull-back action of the needles.

When dispensing wide mix ratios, it is best to use a snuff-back restrictor only on the high volume side.

This keeps the high volume side from being pulled back into the low volume side.

In general, use only as much snuff-back as necessary to give a good cut-off of flow. Too much snuff-back pulls an air bubble into the mixer. This can cause a drip, or cause the mixer to spit when the valve is re-opened.

WARNING

COMPONENT RUPTURE HAZARD

To reduce the risk of over-pressurization, which can cause component rupture and serious injury, never exceed 3000 psi (21

MPa, 207 bar) fluid pressure, or 120 psi (0.84 MPa,

8.4 bar) air pressure to the valve.

D Be sure the air supply lines are connected correctly to the OPEN and CLOSE valve air ports.

D

To open or close the valve and maintain the open or closed status, a minimum of 40 psi (280 kPa, 2.8

bar) air pressure must be supplied and maintained at the OPEN or CLOSE port.

Pressure Relief Procedure

WARNING


The system pressure must be manually relieved to prevent the system from starting or spraying accidentally. Fluid under high pressure can be injected through the skin and cause serious injury. To reduce the risk of an injury from injection, splashing fluid, or moving parts, follow the Pressure Relief Procedure whenever you:

D are instructed to relieve the pressure

D stop dispensing

D check or service any of the system equipment

D install or clean the nozzle

1.

Shut off the air to the dispense valve, if applicable.

2.

Shut off the air to the supply pumps.

3.

Close the bleed-type master air valve (required in your system).

4.

Hold a metal part of the valve firmly to the side of a grounded metal pail, and trigger the dispense valve to relieve pressure.

5.

Open the fluid drain valve (required in your system), having a grounded metal container ready to catch the drainage.

6.

Leave the fluid drain valve open until you are ready to dispense again.

If you suspect that the dispense needle or hose is completely clogged, or that pressure has not been fully relieved after following the steps above, very slowly loosen the hose end coupling and relieve pressure gradually, then loosen completely. Now clear the needle or hose.

D The trigger only activates the electrical switch in the handle, which turns the remote solenoid on and off.

D Trigger the gun to turn the solenoid on. Release the trigger to turn the solenoid off.

Machine Mount Valve

D

Be sure the air supply lines are connected correctly to the OPEN and CLOSE valve air ports.

D To open or close the valve and maintain the open or closed status, a minimum of 40 psi (280 kPa, 2.8

bar) air pressure must be supplied and maintained at the OPEN or CLOSE port.

To open the valve:

1.

Apply air pressure to the OPEN air port on the valve, and remove air pressure from the CLOSE air port on the valve.

2.

Maintain air pressure on the OPEN air port to keep the valve open.

To close the valve:

1.

Apply air pressure to the CLOSE air port on the valve, and remove air pressure from the OPEN air port on the valve.

2.

Maintain air pressure to the CLOSE air port to keep the valve closed.

309000 13

Air Switch Hand Held Valve

The valve operation is such that there are only two valve conditions: either fully open or fully closed.

The valve is opened and closed by the internal air control valve. Trigger the gun to open the valve.

Release the trigger to close the valve.

Operation

Ratio Checking

The output mix ratio of your proportioner can be checked by dispensing the two fluids separately out of the nosepiece into tared cups. The cups can then be weighed and the weights divided to get the mix ratio by weight.

A divided outlet accessory (Part no. 626611) is available to make regular ratio checking easier. This accessory fits the non-wide ratio valves and uses a

512292 retainer nut.

Ratio checks provide information on the ratio of an overall sample. Transient problems (soft spots) caused by starting and stopping the flow (lead-lag) may not show up in this kind of ratio check. Physical tests of the mixed fluid are the best check of correct ratio and mix quality.

14 309000

Maintenance

Preventative Maintenance Daily Shut-down

When you are through using the 2K-UL valve, the outlet to the mixer should be cleaned and protected from drying or crystallization.

There is a grease filled secondary seal/bearing area on each valve shaft. Every 10,000 cycles, or twice each month, new grease should be flushed across this area.

Each valve has two flush grease fittings. A small grease gun is provided with each valve.

WARNING

TOXIC FLUID HAZARD

Hazardous fluid or toxic fumes can cause serious injury or death if splashed in the eyes or on the

Skin, inhaled, or swallowed.

3.

Lubricate and reassemble the piston assembly; piston (10), o-rings (9), dowel pin (7), nuts (8), and o-ring (6), and air cylinder shaft (3). Tighten nuts

(8) to 15–20 in-lb (1.7–2.2 N

S m). The shafts (3) should hang with some play to be self-aligning in the bearing.

4.

Lubricate the air cylinder (1) ID with the grease supplied. Push the piston (10) assembly into the air cylinder.

5.

Insert “C” clip (12). Orient clip opening in front of air passage way.
