Clippard offer various shuttle and needle valves that allow flow from one inlet whilst blocking the other inlet.
Exhaust occurs at the port where pressure was last applied. Can be mounted directly to valves & cylinders or inline using hose barbs on certain models. Adjustable control needle valves restrict the flow in both directions through various configurations to provide coarse or fine flow.


Adjustable control needle valves restrict flow in both directions. There are eight models offered by Clippard with various ports and needle configurations to provide coarse or fine flow adjustment. The diagram of needle shapes and the part show the difference between these models.

• #10-32, 1/4″ NPT, 1/8″ NPT and 3/8″ NPT Ports
• Direct, in-line or cartridge mounting
• Brass or ENP body, ENP or stainless steel needle, Nitrile seal
• Screwdriver or knurled knob adjustment

More Information

Clippard has the broadest product line in the miniature and sub-miniature pneumatic product market with special application to the Bio-Medical industry. Founded by W. L. Clippard, Jr. in 1941, the company started out in manufacturing electronic test equipment. In the 1950’s, Mr. Clippard recognised a need for miniature pneumatic devices in manufacturing and began to produce a small line of component products. The appeal of these products was such that, by the late 1960’s, Clippard Instrument Laboratory was strictly a pneumatic manufacturer. The company has continued to have steady growth through the years with introductions of new and innovative products.
Well known are Clippard, for the original design & manufacture of the famous “Mouse Valve.”

Note: That all products are now available in both Metric & Imperial thread forms.
