PSVPressure Safety Valve ? Conventional Pressure Valve >> Description Generally, the safety valve are referred to the conventional type pressure relief valve, the most common type. The load of the spring is designed to press the “Disc” against the inlet pressure. Depending on the fluid type, such as steam, gas or liquid, we are offering a bellows model to clear the back pressure effect.>> Specification (Same as Pilot Operated Safety Relief Valve) Applicable fluid Gas / Vapor / Liquid Applicable pressure(Bar) Maximum 250 Applicable temperature Maximum 500 End connection ANSI 150LBS ~ ANSI 2500LBS Material (Body : A351CF8M / B148-C95800 / Alloy 625 / A216WCB) (Trim : 316SS / Alloy 625 / MONEL) ? Pilot Operated Safety Relief Valve >> Description Pilot type pressure relief valve are composed of pilot assembly and main valve. There is no adjusting function in the main valve. Pilot type valves have larger size variations compared to conventional type, which is applied in as severe condition such as high pressure. >> Functional Qualification Test (Including Conventional Pressure Valve) Applied Standard : ASME PTC 25 Popping Test completion Blow down Test completion Pressure Relief Device (PRD) Test completion
