Pressure Sealed Check Valve

Cast Check ValveHuachao Cast Check Valves are designed and manufactured strictly to international standards API 6D, BS1868, ASME B16.34 or equivalent, to reduce the flow resistance and pressure drop to the minimum possible extend which is suitable to be mounted in horizontal position only, lapped and screwed in seat ring ensures tight shut off and long duration service. Valve’s disc is perfectly designed, accurately machined and guided for efficient automatic shut off at zero pressure, with a feature of compact structure & low emission service in both swing & piston constructions.Hot tags: Cast Check Valve, China manufacturer, factory, mill, supplier, cheapPressure Seal Check ValveHuachao Pressure Seal Check Valves are intended for high pressure high temperature applications in all types of fluid except where severe coking is a factor. The design and material selections provide excellent service in steam-generation stations, industrial chemical plants and thermal power plants. Huachao pressure seal check valves provide the most efficient flow passage and sealing features possible, resulting in a significant weight saving, easy installation and in-line maintenance.Features:Size ranges: 1 1/2" to 24"Pressure ratings: class 600 to class 2500, PN110 to PN420Structured in bolted or pressure sealed union coverEnds connection in flange (R.F. or RTJ, thread NPT, BSPT, S.W., B.W. and grooved)Material: carbon steel, A216, WCB, WCC, LCB, LCC, alloy steel, A217, WC6, WC9, stainless steel, A351, CF8, CF8M, CF3, CF3M, duplex & super duplex steel, A890, Gr.4A, Gr.5ATrim material: 13Cr, F11, F22, SS304, SS304L, SS316, SS316LDesign & manufactured to API 6D, ASME B16.34P.T. rating to ASME B16.34Face to face dimensions to ASME B16.10Flanged ends to ASME B16.5Butt-weld ends to ASME B16.25Thread ends to ASME B1.20.1Socket-weld ends to ASME B16.11Valve marking to MSS sp-25Inspect & tested to API 598
