Routine Cleaning and Disassembly 
 

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

parts kit, part # 

FCM1-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)

 

Using the tip of a 3/32” Allen key, loosen the packing nut (6). 

4)

 

Using the same 3/32” Allen key, evenly remove the two machine screws (22) that 
are located on the same corners as the fluid section standoffs (4). Note: During 
removal that there is a spring (18) forcing the air section away from the fluid 
section. 

5)

 

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

6)

 

Clean off the tip of the stainless steel needle (3). 

7)

 

From the fluid section of the valve, unthread and remove the packing nut (6), and 
the packing (5). 

8)

 

Unthread and remove the nozzle lock nut (12) followed by the nozzle (17).  

9)

 

Unthread and remove the nozzle adapter (1) from the fluid section (4). 

10)

 

Using pliers, pull the seat (2) out of the fluid section (4) and remove the 006 
Kalrez o-ring (16) 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 (21) that thread into the end cap (7). Note: During removal that 
the spring (18) will force the air section apart. 

13)

 

Separate the upper air body (10) from the lower air body (8) to remove the spring 
(18) then slide the end cap (7) off the needle (3). 

14)

 

Holding the lower air body (8) in one hand, grab the needle (3) and push the 
needle and piston (9) assembly out of the lower air body. 

15)

 

Remove the 004 Buna o-ring (15) from the lower air body (8). 

16)

 

Hold the piston (9) with an adjustable wrench then using the 5/64” Allen key 
unthread and remove the set screw (19) to remove the needle (3) and remove the 
014 Buna o-ring (13) from the piston (9). 

17)

 

Remove the 014 Buna o-ring (13) from the upper air body (10) then use a 1/16” 
Allen key to remove the set screw (20). 

18)

 

Using pliers grip the collar (E) or body (D) of the micrometer (11) and turn 
counter-clockwise to loosen then unthread and remove from the upper air body 
(10) by hand. 

19)

 

Remove the 007 Buna o-ring (14) from the micrometer (11). 

 

 

Replace components with spares provided in the spare parts kit.
