To disassemble the pressure vessel
(Ref. Figure 3)
Caution:
Do not use a pipe wrench directly on the sleeve
tube.
These valves contain a hex style flange in the sleeve as-
sembly. A wrench may be applied directly to the hex
flange in order to loosen the sleeve assembly. Unscrew
the sleeve assembly. The plunger and return spring may
now be removed. Maximum retightening torque is 270
inch-lbs (30.5 N-m).
Unscrew the four (4) cover screws. If the cover cannot
be easily lifted off the body, laterally tap the cover or gen-
tly pry the cover from the body with a screwdriver. Care
must be taken not to damage diaphragm, cover, or body.
Diaphragm return spring(s), diaphragm assembly, and o-
rings can now be removed. Maximum retightening torque
on cover screws is 135 inch-lbs (15.25 N-m).
Replacement Parts:
When ordering replacement parts
kit, specify part number (P/N 6999991583). Parts includ-
ed in each kit are marked with an asterisk (*). See ex-
ploded view, Figure 3.
Maintenance of Emergency Station Valve
This valve, Item 2, is not field serviceable. In the
event that leakage is occurring it must by replaced
with a new manual emergency releasing station. Re-
placement is made by removing the coupling, Item
33 and loosening the union, Item 46, and then un-
screwing the segment of piping which begins with
nipple, Item 16, at the inlet to the valve. When order-
ing replacement valve, Item 2, also order two clamp
rings, Item 22, for remounting the nameplate base,
Item 36. Make certain both new clamp rings have
been slipped onto the nipple, Item 16, above the
valve before the new valve is attached to this nipple.
After all piping is reconnected, reposition the name-
plate, as shown, and tighten the new clamp rings
over the two nameplate tabs using crimping pliers to
draw the bands tight.
