The quick release valve (QRV) is a pneumatic in-line,three-way valve designed to automatically close upon pressurization and open to exhaust when a pressure drop occursin the supply line. The valve provides an exhaust port close to the pressurized chamber of the device being controlled rather than exhausting through long supply lines and/or control components. The end result is a reduction in lag time between the signal to exhaust and response. The benefits derived include:Faster cyclic rates,Reduction or elimination of overlap,Reduced wear of drive components.
