Aldrich^® adjustable pressure-release valve

Automatic, adjustable pressure relief valve is for use on apparatus where internal pressure build-up is a concern. Can be mounted into a vacuum rack to allow rapid purging of an inert gas without damage to system. Also useful for freezing applications. Two-piece PTFE plug with Viton^® O-ring and SS spring is adjustable for pressures of 5 to 50 psi. The tension on the spring determines the amount of pressure needed to force the lower part of the two-piece PTFE valve plug to open.
