Operation

Refer to assembly drawings 112-2998 & 112-3616 for part reference numbers.

1) Plumb up the valve as outlined above in the Setup procedures.

2) Fill the air motor lubricator with oil (27001) provided with the valve.

3) Regulate the air pressure operating the FC100-Module portion of the valve

between 60-100psi.

4) Making sure that the coating nozzle is inserted into a protective cylinder, cycle the

valve several times. When the valve is cycling, the needle (1A) can be seen going

up and down in the center and the air motor will be spinning the rotary shaft (3).

If the air motor is not spinning, increase the air pressure until it begins to turn.

The air motor typically requires a minimum of 20 psi in order to start spinning.

5) Again, cycle the valve several times to ensure the valve is opening and the air

motor is spinning with each cycle.

Note: If the valve is not cycling properly, refer to the Troubleshooting section.

6) When the fluid delivery system is connected to the valve, pressurize the material

to be dispensed. The suggested starting pressure range is less than 5 psi.

7) Again, insert the nozzle of the valve into a protective cylinder in order to contain

the material that will be sprayed.

8) Once again, cycle the valve open to purge. Fluid should begin to spray in a 360’

degree pattern from the output of the coating nozzle.

9) Check the fluid connection and packing nut (16A) for leaks. If the valve is

leaking, refer to the Troubleshooting section.

10) Adjust the fluid pressure in order to control the rate of fluid flow to the spray

nozzle.

11) The stroke adjustment (12A) can also be used to fine tune the fluid flow. Turning

the adjustment clockwise will decrease the material flow rate and counter-

clockwise will increase the material flow rate. If the stroke adjustment bolt is

turned all the way down it will stop the flow of fluid entirely.

12) Once the stroke adjustment setting is determined, use the adjustable wrench to

tighten the lock nut (11A) up against the upper air body (10A).

Note: Refer to Troubleshooting section for any problems.

Periodic Maintenance

1) Visually check the see through chamber of the air motor lubricator daily and refill

when it runs empty.

2) Lubricate the packing (15A) on the FC100-Module every 200 hrs by placing a

few drops of mineral oil or other light oil inside the packing nut.

*Note: PVA offers a 2.5cc mineral oil lubrication kit; Part#: B62-0752

3) The packing nut (16A) will require occasional tightening, as wear occurs in order

to prevent leaks through the packing.

Air Motor Lubricator

The air motor must stay lubricated with a small amount of light oil in order to

maintain a long usable life. An air motor lubricator and oil are supplied with the RC200

valve. The oil level can be seen through the clear chamber on the bottom section of the

lubricator. When the oil runs out it will be necessary to refill the chamber. To do this

simply unthread and remove the clear chamber to separate the sections. These parts

should separate easily. Once removed, fill the clear chamber about half way with air

motor oil and thread the chamber back onto the housing, hand tight.

*Note: PVA offers additional tubes of air motor oil; Part#: 27001

*Note: During this operation, be sure air pressure is removed from system.

Routine Cleaning and Disassembly

Cleaning and rebuilding the valve will be required from time to time. A spare

parts kit, part # RC2-SP is available with all the normal wear parts included.

1) Begin disassembly by removing air and fluid pressure from the valve.

2) Remove all pneumatic tubing and fluid delivery fittings, hoses, etc. from the

valve.

3) To remove the coating nozzle (2), place the M7 wrench on the flat of the rotary

shaft (3) and use the pliers to grab the coating nozzle, turning counter-clockwise

to remove.

4) Using the 3/32” Allen Key, unthread and remove the four machine screws (9) that

connect the FC100-Module to the fluid section of the RC200.

5) On the FC100-Module use the 3/32” Allen key to loosen the packing nut (16A).

6) Using the same 3/32” Allen key, evenly remove the two machine screws (3A) that

are located on the same corners as the standoffs (6A). Note during removal that

there is a spring (5A) forcing the air section away from the fluid section.

7) Pull the air section (red anodized portion) away from the fluid section (stainless

steel portion).

8) Clean off the tip of the stainless steel needle (1A).
