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).
9) From the stainless steel fluid section of the valve, unthread and remove the
packing nut (16A), and the packing (15A).
10) Using the pliers pull the seat (13A) out of the fluid section (14A) and remove the
006 Kalrez o-ring (18A) from the seat. Note: If stuck, the seat can be pushed
through from the opposite side of the fluid section.
11) Clean all of the wetted parts thoroughly with an appropriate solvent.
12) On the air section, use a standard 3/32” Allen Key to evenly remove the final two
machine screws (2A) that thread into the end cap (7A). Note: During removal that
the spring (5A) will force the air section apart.
13) Separate the upper air body (10A) from the lower air body (8A) to remove the
spring (5A) then slide the end cap (A) off of the needle (1A).
14) Holding the lower air body (8A) in one hand, grab the needle (1A) and push the
needle and piston (9A) assembly out of the lower air body.
15) Remove the 004 Buna o-ring (17A) from the lower air body (8A).
16) Hold the piston (9A) with an adjustable wrench then use a 5/64” Allen key to
unthread and remove the set screw (4A) to remove the needle (1A) then remove
the 014 Buna o-ring (20A) from the piston (9A).
17) Remove the 014 Buna o-ring (20A) from the upper air body (10A) and the 008
Buna o-ring from the stroke adjust bolt (12A).
18) Unthread the stroke adjust bolt (12A) from the upper air body (10A) and remove
the 008 Buna o-ring (12A).
19) On the fluid body (4) of the RC200 remove the 010 Kalrez o-ring (12) that sealed
against the FC100-Module.
20) Using the 3/32” Allen Key, remove the plug (11) from the fluid body (4).
21) Using the 1/16” Allen Key, loosen the set screw on the rotary shaft (3).
22) To remove the air motor (7) use the 9/64” Allen key to unthread and remove the
two machine screws (10) then slide the air motor away from the motor mount (5).
23) The rotary shaft (3) can now be pushed through the valve and removed through
the motor mount (5).
24) Using the 3/32” Allen Key, remove the two machine screws (9) that secure the
motor mount (5) to the fluid body (4) and separate the two sections to remove the
010 Kalrez o-ring (12).
25) Using the same 3/32” Allen Key, remove the two machine screws (8) that secure
the seal plate (6) to the fluid body (4) and separate the two sections to remove the
final 010 Kalrez O-Ring (12).
