Mounting
2.2.1
Screw the cylinder port of the quick release valve into
the female port of the device using a minimum of
pipe thread sealant. Use a wide, flat faced wrench
which will not crimp or damage the valve body. The
quick release valve must be torqued enough to pro-
duce a tight seal, but not more than the value given in
Table 4.
Do not position the quick release valve
exhaust port in the up position or allow for-
eign matter to enter the valve housing. Parti-
cles of foreign matter will enter the exhaust
air stream and/or prevent diaphragm seating.
Either condition could result in personal
injury or damage to equipment.
Position the quick release valve exhaust port
so that the exhaust air stream does not
strike operating personnel. Particles of for-
eign matter picked up by the air stream can
cause personal injury.
Position the quick release valve exhaust port
so that there are no restrictions to the
exhaust air flow. Any restriction will slow
down the valve response time.
2.2.2
If the quick release valve has pipe threads on the
inlet port, make a direct pipe connection. Do not
exceed the tightening torques given in
Table 4.
2.2.3
For quick release valves having tubing connections,
slide the nut and sleeve onto the inlet air tubing and
insert the tubing or pipe adapter into the valve hous-
ing until it bottoms. Slide the sleeve into its seat in the
housing. Tighten the nut sufficiently to produce an air
seal but not more than the value given in
Table 4.
2.2.4
If a muffler is to be used, install per the following
instructions.
Loctite® must be used where called for in
the following procedure. Mufflers installed
without Loctite® may work loose during
operation resulting in personal injury.
Note : Quick release valves supplied prior to Sep-
tember, 1989 do not have threaded end caps to
accept the muffler. The end caps on these valves
must be replaced. Refer to the Maintenance sec-
tion in this manual for end cap replacement.
Note : Mufflers are not factory-assembled to the
quick release valves due to possible interference
with the rims of Airfiex clutch elements. When a
quick release valve having a muffler is ordered, a
basic valve is supplied along with a muffler/end
cap/diaphragm kit. If only the muffler is to be
installed, discard the end cap and diaphragm
included in the kit.
2.2.4.1 Thoroughly clean the female threads in the quick
release valve end cap and the male threads on the
muffler.
2.2.4.2 Apply Loctite
®
#222 (included in the kit) to the
threads on the muffler, using one drop per thread,
and screw the muffler into the end cap. Torque the
muffler to 60 lb.-in. (7 Nm).
2.3
Testing
2.3.1
Apply air pressure to the quick release valve. The
valve and its connections should not leak under pres-
sure. If the valve leaks, refer to the Maintenance sec-
tion in this manual.
2.3.2
Cycle the valve several times to ensure proper oper-
ation. If the valve response time appears sluggish,
check for restrictions in the air supply line.
