TO TAKE THE SOLENOID VALVE APART
DISASSEMBLY - These valves may be taken apart by unscrewing
the bonnet and the enclosing tube assembly from the valve body
assembly. After unscrewing, carefully lift off the bonnet and enclos
-
ing tube assembly. Don’t drop the plunger. The o-ring seal and
diaphragm cartridge can now be lifted out. Be careful not to dam
-
age the machined faces while the valve is apart.
TO REASSEMBLE - Place the diaphragm cartridge in the body with
the pilot port extension UP. Hold the plunger with the synthetic seat
against the pilot port. Make sure the o-ring is in place, then lower
the bonnet and enclosing tube assembly over the plunger. Screw
the bonnet assembly snugly down on the body assembly.
