A.
Standard pinch valves are
built to schedule 40 pipe I.D.
and to ANSI Class 125/150#
flange and bolt circle specifica-
tions. It is recommended that
the mating flanges are flat and
full faced.
B.
It is recommended that the
mating flange be serrated to
"grip" the rubber flange. The
serrations should be cut 1/16"
deep, with a 90 angle tool
point. the pitch should be 8
(eight) cuts per inch.
C.
Mating flange ID must match
the pinch valve
sleeve ID.
D.
When installing a pinch
valve to a rubber, PVC, or any
"slick" mating flange, we
recommend that you install a
metal serrated gasket between
the two flanges to assist in
the seal.
E.
When bolting a pinch valve
to a PVC or synthetic mating
flange, use a split back-up
retaining ring, since the mating
flange will yield prior to
generating enough force on the
flange faces for a proper seal.
F.
Torque all the flange bolts in
a star pattern, first to 50% of
tabulated valves, then retorque
to 100% of tabulated valves. If
greater torque is required,
continue retorquing in incre-
ments of 50% of tabulated
valves. Use of high quality anti-
seize compound on all bolt
threads is recommended.
Variables such as the surface finish on bolt threads, type of
anti-seize compound used, and surface finish of the mating
flanges all have an effect on the minium torque required to
obtain a leak-tight flange seal.
