An engineering team at Humphrey Products has engineered a one-piece pneumatic diaphragm valve for use in a medical anesthesia machine. The brass-body valve includes an integral pilot actuator and reportedly operates with zero leakage at 50 psig. Its design represents a departure from traditional anesthesia machine valves, which typically use a two-piece configuration that incorporates sliding seals. In contrast, Humphrey's valve employs a diaphragm that incorporates no sliding seals, and therefore can operate precisely for millions of cycles.
