2.0 ACCESSORY MAINTENANCE (REFER TO FIGURE 2)
The accessories used on the Type 95 are the auxiliary setter, field test and backflow
preventer. The field test and backflow preventer are always used; the auxiliary setter
is optional.
Only the backflow preventer, which consists of one
ball check valve requires maintenance. Normal maintenance is to clean the check
valves and replace the diaphragm, washer, gasket,
When replacing the diaphragm, care should be taken not to damage the diaphragm. To
assemble the diaphragm type valve, uniformly tighten the body bolts, first one side, then
the opposite side. Do not overtighten the bolts as this will distort the diaphragm and
cause leakage.
NOTES:
(1)
Gasket used on some check valves. If check valve has gasket, use gasket
supplied in repair kit - otherwise discard kit gasket.
(2)
Some earlier model valves use two diaphragm check valves and no ball check valve.
