TO TAKE THE SOLENOID VALVE APART
DISASSEMBLE - These valves may be taken apart by unscrew
ing the bonnet and the enclosing tube assembly from the valve
body assembly. After unscrewing, carefully lift off the bonnet and
enclosing tube assembly. Don’t drop the plunger. The o-ring seal
and diaphragm cartridge can now be lifted out.
Be careful not to damage 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 syn
thetic 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.
