Repair Instructions
Procedure
Make sure that the valve internals that are
subject to vacuum remain clean. Use lint free wipes
as necessary and keep seals free of contaminants.
1. Shut off the air supply to the air solenoid.
2. Remove the air fitting at the center plate (4).
3. Remove the air cylinder (1), apply 30 to 40 lbs. of force
against the top of the air cylinder (1) to neutralize the
spring (9) while removing the bonnet screws (13).
4. Remove valve internals from the body (7) and inspect
body flange O-ring (15) and poppet O-ring (17) and
replace if necessary.
5. If the bellows assembly (16) requires replacement,
remove the jam nut (11) by first inserting a 7 / 16 " open
end wrench in the stem shaft (5) to keep the bellows
assembly (16) from rotating while removing the
jam nut (11). Remove piston cup (12) and slide off
center plate (4). Remove set screw (6) and replace
the bellows assembly (16).
6. Replace all O-rings as necessary including the piston cup (12).
7. Apply a light film of high vacuum grease on the O-rings
prior to installing them.
8. Apply anti-seize or equivalent on set screw (6)
and on bonnet screws (13).
9. Apply Lubriplate ® high temperature grease
#PTL0161-001 or equivalent on stem shaft (5).
