Step 8.
Ensure that the unions and flare
fittings are securely tightened.
Step 9.
With the Diaphragm Supply
Valve (P) closed, fully open the Inverted
Flare Shut-Off Valve (R) stainless steel
screw (approximately 1/2 in.) until resis-
tance is met so as not to break the
internal roll-pin. The internal roll-pin
stops the removal of the Inverted Flare
Shut-Off Valve (R) stainless steel screw.
Step 10.
Proceed with Step 5 of the
Valve Setting Procedures section in this
data sheet.
NOTICE
If the water supply contains chemicals
which tend to attack a polyester fabric-
reinforced, EPDM rubber or the five year
inspection indicates a build-up of debris
within the
DV-5
a
Valve
that could affect
its proper operation, then the frequency
of the internal valve inspection procedure
must be appropriately increased.
With reference to Figure 1, make
certain that the Diaphragm is correctly
oriented; otherwise, the DV-5
a
Valve
cannot be properly set.
Under-tightening the Diaphragm Cover
Bolts can result in internal and external
leakage.
Use only TYCO replacement fasteners
as specified in Figure 1.
Do not apply adhesives, lubricants, or
other substances to the Diaphragm
Valve Body.
