Anticorrosion 304ss Pressure Safety Valve (300lb-3")

Model NO.: A42Y Temperature: -24 ~ +250 Deg C Pressure: Adjustable Structure: Angle Connection End: Flanged End Standard: ASME B16.5 Transport Package: Export Package Origin: Zhejiang, Cn Certification: ISO, CE Connection: Flange Closed: Open Material: Alloy Test Inspection: API 598 Trademark: ONEV Specification: ANSI HS Code: 84814000 High Performance Bellows Balanced type Pressure Relief Valve 

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 

FEATURES
 

RADIATOR DEIGN	For safety valve over 350 DegreeC, the radiator strcuture will be applied to suit high temperature conditions, the radaitor will help to disperse heating and protect the spring form overheating circumstances so as to ensure the stability of spring.
HIGH PERFORMANCE SPRING	Only high grade spring is selected for operation for safety valve, the spring has been gone through strictly test including physical and chemical analysis so as to ensure the best stablity and safety for operation.
FINE STEM PROCESSION	The stem was processed by CNC machine to give 100% vertical so as to make sure the smoothly opening and blowing of the safety valves.
DOUBLE ADJUST TING	Double adjusting ring are used for blow down adjustment, we give fine procession of adjusdting ring to give smoothly adjusting for safety valve.
NOZZLE AND DISC	The surface of both disc and nozzle seat is deposited with hard alloy of Stellite, and the excellent surface treatment by precision machining and lapping ensure the tightness and stable performance during the operation.
