Service Procedures
To disassemble unit, use the following procedure:
To detach the hand toggle, cam head, or button actuator assembly
from the valve body assembly, remove the 4 pan head screws (using
a Philips screwdriver). To remove the stem, stem guide, and seals
from the body, unscrew the end plug using a 3/8" Allen wrench.
Then gently press on the “pin” side of the stem until it slides out of
the body. The stem guide may be removed by pulling axially on the
radial holes drilled in the stem guide. Be careful not to scratch the
sealing surfaces or cut the seals.
Thoroughly clean the valve body bore and stem guide, and inspect
for possible nicks, scratches and material imperfections. Lightly
lubricate the stem seals. (Use a non-detergent hydro-carbon
based oil or grease.) Replace any o-rings or other seals if they are
damaged.
The Assembly procedure is the reverse of the above. Tighten the
end plug to 60 in-lbs and apply 15-18 in-lbs of torque to the pan
head mounting screws.
If you have questions concerning how to service this unit,

Installation & Operating Instructions
Valve should be installed with reasonable accessibility for service
whenever possible - repair service kits are available. Keep pipe or
tubing lengths to a minimum with inside clean and free of dirt and
chips. Pipe joint compound should be used sparingly and applied
only to the male pipe - never into the female port. Do not use PTFE
tape to seal pipe joints - pieces have a tendency to break off and
lodge inside the unit, possibly causing malfunction.
Filtered and lubricated air is necessary for maximum valve life and
minimum maintenance.
Factory Pre-Lubrication - All valves are pre-lubricated at assembly
with a petroleum based grease.
Valve Operation
These valves will operate mounted in any position; they are also
suitable for vacuum service.
