Model NO.: A21H Connection End: NPT, Nptf Body: ASTM A216 Wcb Trademark: ONEV Origin: Zhejiang, Cn Structure: Lever, Angle Inspection Test: API 598 Spring: 50crva Specification: ANSI HS Code: 84814000 Application:
A pressure relief valve (PRV) is a safety device that relieves overpressure in a vessel or system. When the pressure of vessel or system increased beyond the specified design pressure or maximum allowable working pressure, PRV will be opened automaticly to relief the overpressure for proteding the vessel or system. The PRV will be closed if the pressure reached specified design pressure so that to ensure the normal operation and protect the vessel or system.
Our Pressure Relief Valve has been designed and manuractured according to following Standard:
ISO 4123-1 Safety Devices for Portection Against Excessve Pressure
API STD 526 Flanged Steel Pressure Relief Valves
API STD 527 Seat Tightness of Pressure Relief Valves
ASME Boiler and Pressure Vessel Code Section VIII Division 1, Rules for Construction of Pressure Vessels
