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.
