The Acrylic Pneumatic Circuit Boards are designed to provide a mounting base for Modular Valves and a Pneumatic Control System for the various Modular Valve Circuits.

Originally developed for use strictly in conjunction with Clippard’s modular valves, the line of acrylic sub-plates today has expanded to include the company’s electronic valves as well. These manifolds are constructed of multiple layers of acrylic that has been machined and laminated to give a ready-to-install logic circuit. This reduces assembly time and trouble-shooting to find leaks and incorrect connections. Clippard offers a variety of standard circuits for applications such as ‘two-hand no tie down’ safety, ‘automatic cycling without limits’ and ‘oscillation’ circuits.




Custom made circuit boards provide a secure mounting surface for all components.

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.
