Small Orifice Pressure Relief Valves

Features:

1. ASME UV certified, and capacities are certified by the National Board Boiler and Pressure Vessel Inspector.
2. Applies to the safety protection all kinds of pressure-bearing devices in petro-chemical, chemical industries where thermal expansion relief of tanks and pipelines are needed.
3. For metal sealing, the sealing surfaces are deposited with Stellite. Excellent flatness and surface finish of sealing surfaces by precision machining and lapping assures seat tightness and long life.
4. For non-metal sealing, the anti-creeping non-metal sealing material with outstanding performances are used to guarantee tight sealing under ambient and cryogenic conditions.
