Materials : CS, LTCS, SS & Duplex, Etc. Flanged End : ASME B16.5 Flanged End, RF/RTJ Face-to-face or End-to-end : ASME B16.10 Wall Thickness & General Design Code : API 600, ASME B16.34 Pressure Rating : ASME Class 150 to 1500 Size Range : NPS 2(DN 50) to NPS 30(DN 750) Special cleaning for applications such as oxygen or chlorineīolted Cover/ Swing Type, Lift Type & Piston Type/ Outside input Hinge Pin and Arm joint/ Full Port/ Flanged Ends or Butt-weld Ends Gear, motor, and cylinder actuators available Bypass, drain and other auxiliary connections Swing check valve with flanged end pressure is available from Class 150 to class 2500 lbs, face to face according to ANSI B16.10, manufactured to BS 1868 ANSI B16.34 or API 6D full port ,pressure tested according to API 598. Alternate valve materials such as chrome and stainless steel alloys We manufacture check valve mainly used on water, gas oil, steam, petrochemical, oil and gas industries. Carrier Pin is confined within the body wall and is not accessible from the exterior, thus no side body penetrations, eliminating a common leak path, on classes 150 through 600.Įnd Flanges have the following raised faces per ASME B16.5: Classes 150-300: 1/16” (2mm) Classes 600-1500: 1/4” (7mm).Įach valve has a unique certification number that is traceable to the valve certification sheet which includes MTR data, pressure test, inspection result and certificate of conformance. Check valve are suitable for service in horizontal line with cap vertical or in a vertical line with flow upward. Each valve is shell and seat pressure tested per industry standard API 598. Swivel disc for improved seat alignment and longer life. Wall thickness per heavy wall API 600 requirements. Seat faces lapped for smooth finish and superior sealing.

Other trim materials available on request. Valves can be supplied in other MOCs on request:. Standard trim is API trim 8 for carbon steel valves, API trim 5 for chrome alloy valves, and API trim 10 for CF8M (T316) valves for optimal performance under normal conditions. CAST STEEL SWING CHECK VALVES- BS 1868, API-6D, ASME B16.34. And It’s built up with BS 1868 additionally for Swing check valve. DongsanValve’s Cast steel valve are constructed with design of API 600, ASME B16.34 & API 6D.
