Wafer Dual Plate Check Valve

Dual Plate Check ValveHuachao Dual Plate Wafer Check Valve has One Piece cast heavy stronger Body configuration provides reduced weight and size compare to a swing check valve or lift check valve. This results in saving Initial cost, space and pipe support element installation. The Dual Plate, Wafer Check Valve employs two-spring-loaded plates hinged on a central hinge pin. When the flow decreases, the plates close by the action of torsion spring before flow reversal takes place. All features put together make the Dual Plate Check Valve as the most efficient & versatile design. It is also referred to as SILENT CHECK VALVE It is much easier to install between standard gaskets and line flanges, and therefore is more cost effective to install and to maintain. Its design complies with API 594 and API 6D, testing to API 598.» Sizes Ranges from 2" through 60".»Material:stainless steel ,carbon steel» Pressure Ratings from Class 150 to Class 2500, PN16 to PN420» Design & Manufactured to API 6D, API 594, ASME B16.34 or Equivalent» P.T Ratings to ASME B16.34» Face to Face Dimensions to ASME B16.10 » Flanged Ends to ASME B16.5» Butt-weld Ends to ASME B16.25» Valves Marking to MSS SP-25» Inspect & Tested to API 598» Structured in One Piece Union Body » Ends Connections in Flanged R.F or RTJ, Wafer, Fully Lugged and GroovedHot tags: Dual Plate Check Valve, China manufacturer, factory, mill, supplier, cheapWafer Dual Plate Check ValveRetainerlessRetainerless is standard in Huachao Check ValvesNo screwed body plugsNo leak path to atmosphereEmissions free designNo Fugitive EmissionsAPI 594» Sizes Ranges from 2" through 60".»Material:stainless steel ,carbon steel» Pressure Ratings from Class 150 to Class 2500, PN16 to PN420Designed in accordance with API 594Face-to-face dimensions to API 594Patented Plate DesignPressure sensitive plate.Improved flow efficienciesTotal Life Cycle Costs reducedSuperior metal-to-metal sealingHigh degree of shut-off
