Medical gas valve D688

stainless steelhigh-pressure

Combined soft and metal seat design with low permeation rate. Welded diaphragms provide a high leak tightness integrity Tied diaphragm design which minimizes gas wetted volume to allow easy purging. No moving components in the gas wetted area to not generate particles. Secondary sealing to prevent the gas coming in contact with actuator in the case of diaphragm failure. Threaded weep hole for leak test and pipe away connection (M4 thread), allows the connection to a leak detector.
