Clippard Receives Patent for Proportional Isolation Valve

Clippard Instrument Laboratory Inc., a manufacturer of precision flow-control products with focus in the medical, analytical, liquid/gas delivery, laboratory, and industrial automation markets, announced that the U.S. Patent and Trademark Office has issued a patent for Clippard’s new Eclipse proportional valve. The patent, Flow Control Valve Using Ceramic Valve Members, expires in 2040.

The patent covers “a flow control valve that uses two ceramic members having conforming surfaces which are coupled together to form a fluid-tight seal, and slidable relative to each other to control fluid flow. The shape of the ceramic apertures and their interaction when the valve is opened and closed permits ultra-fine control of the flow of gas or liquid,” Clippard said in a press release.

Using a robust and powerful miniature linear actuator, the patented stepper-controlled Eclipse proportional isolation valve is ideal in critical applications for liquid or gas delivery requiring ultrafine resolution and excellent repeatability. In addition, the unique design allows for custom flow profiles.
