Operation method The valve clack can be automatically opened and closed with the medium force, movement weight can be increased to facilitate fast closing of valve clack, hydraulic cylinder can be increased to facilitate slow closing of valve clack to prevent vibration of pipeline, and pigging can be performed through manual opening and locking the valve clack at the opening position.
Application fields For application in fields such as electric power industry, petroleum refining, petrochemical engineering, offshore oil, tap water engineering in urban construction, chemical engineering, etc.
Other remarks 1 The sealing faces of valve seat and valve clack are build-up welded with hard alloy to improve the erosion resistance and extend the service life of valve.
Other remarks 2 SS+ graphite or metallic seal or pressure self-sealing is adopted between valve body and bonnet for reliable sealing.
Other remarks 3 Suitable for medium backflow prevention in pipeline or device
Other remarks 4 Large check valves are designed with hydraulic damping cylinder to prevent the valve clack from bumping the valve seat, damaging the valve or causing pipeline vibration due to fast closing.
Other remarks 5 In case of pigging requirement, API 6D swing check valve can be manually operated to fix the opening position of valve clack, so as to achieve the pigging objective.

swing check valve is designed and manufactured according to American National Standards (ANSI B16.34) and American Petroleum Institute (API16D). Swing disc with straight channel which can be installed in both horizontal and vertical pipelines. The inner hinge pin can avoid external leakage. Bolted bonnet design. When pressure is higher than Class 600Lb, pressure self-sealing structure is adopted, which can reduce the valve weight and have reliable seal.
