(a) A quantity of one (1) of the seals is required depending on the 

solenoid valve style being repaired. The spring return side of 
the ceram valve dœ s not have piston seals, therefore only the 
piston seal on the solenoid side of the valve requires replace-
ment. Replace the worn seal with a new one of the same 
type.

(b) A quantity of one (1) of the subplate gaskets is required de-

pending on the solenoid valve style being repaired. Replace 
the worn subplate gasket with a new one of the same type.

(c) The QRV diaphragm or the QRV plug is used when rebuilding 

the QRV on the solenoid side of the ceram valve depending 
on the style. If the ceram valve dœ s not have a removable 
QRV seat, install the green diaphragm in place of the gray 
one. If there is a removable QRV seat, discard seat and "O" 
ring and install the QRV plug and new "O" ring. The spring 
return side dœ s not require a diaphragm or plug.

1444A REPAIR KIT

In 1989/1990, the ceram solenoid valve casting design was 
changed which aff ects some of the seals and gaskets. The repair 
kit includes parts for both old and new styles and for double air 
piloted solenoid valves, therefore some parts will not be used in 
the repair of the single solenoid, spring return valves.
