Proportional Valve Could Improve Respirators

From Clippard Instrument Laboratory, Inc.
 

 
Designers of ventilators, respirators, and blood pressure monitors could benefit from a new proportional pneumatic valve that reportedly offers greater air flow control accuracy. The new valve, introduced by Clippard Instrument Laboratory, Inc. (Cincinnati, OH; www.clippard.com) and known as the EVP, uses a design that incorporates only one moving part to improve accuracy and boost its life. "We have a maximum flow accuracy of ±10%," notes Paul Gant, International Sales Manager. "And at a minimum, we expect its life to be between 200 million and 300 million cycles," he adds. Clippard executives say they foresee the new pneumatic valve being employed in mass flow controllers, gas chromatographs, and anesthesia machines, in addition to respirators and ventilators. The valve's long life could make it particularly desirable in such applications where human lives could depend on its ability to keep operating.
