To take the valve apart:
Disassembly — These valves may be taken apart by
unscrewing the bonnet and the enclosing tube assembly from
the valve body assembly. See Fig. 3. 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
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 bonnet assembly snugly down on the
body assembly.
