Inconel Safety Relief Valve
Design Feature:
-Safety Valve/pressure safety valve, angle type;
-Full lift safety valve;
-Conventional type, Standard safety valve for fluids and gas;
-Metal to metal seated;
-Flange connection according to ANSI B16.5;
– Spring load;
-100% Compatibility to API 526
-Single Trim (identical internal parts for steam/gas/liquids) allows economical maintenance;
-Quick delivery for high-alloy materials;
-Longer valve lifespan due to hardened disc and (partially) stellite seat;
-Longer lifespan of optional bellows through integrated shielding
Standards Compliance:
-Design and Manufacture: API 520
-Face to Face(end to end): API 526
-Test and Inspection: API 527
