QUICK EXHAUST VALVES Service Information
ASSEMBLY VIEW The Quick Exhaust Valve speeds the exhausting of your air cylinders, clutches, or other pneumatic devices. Air pressure is vented close to the operated device instead of back through the control valve.
OPERATION
INSTALLATION The Quick Exhaust Valve should be installed as close as possible to the device to be vented. Quick Exhaust Valves are built in either aluminum or plastic body construction, in 1/4" and 3/8" sizes. The 1/2", 3/4" and 1" sizes are built with only the aluminum body. The 1/4" and 3/8" sizes can be supported by piping alone, but mounting brackets are available for installations involving vibration or long pipe runs. Longer body screws are not required. The 1/2", 3/4" and 1" valves have a mounting bracket as an integral part of the cover. The IN and OUT ports are usually on the same center line, but the cover of any of the Quick Exhaust Valves can be rotated in 60 degree steps to accommodate piping. The cover is often rotated 180 degrees to eliminate an elbow fitting in the piping system. This assembly places the IN port at a 90 degree angle to the OUT port.
Maximum operating pressure, temperature, and other Technical Data are shown on page 3 for both the aluminum and plastic bodies.
The Quick Exhaust Valve has 3 ports as shown in the assembly view. Air pressure entering the IN port forces the diaphragm to seal the EXHAUST port and air flows around the edge of the diaphragm to the OUT (Cylinder) port. When air pressure at the IN port is reduced, the pressure is slightly greater at the OUT port, the diaphragm is forced against the IN port. With the IN port sealed off, a direct passage is opened between the OUT port and EXHAUST port, allowing the operated device to vent quickly.
