Quick exhaust valves (QEV)
Description
Quick exhaust valves (QEV) are used to quickly vent a pressurised volume. To do this, the pressure applied to the pilot connection is released and the QEV opens a large cross-section.
QEVs are often used in (spring-return) drives to achieve fast travelling times.
