Swing Check Valves

Swing check valve also known as one-way valve or check valve, its role is to prevent the media flows back in the pipeline. Opening and closing parts by the power of media flow. Check valves are automatic valves, mainly for the medium one-way flow of the pipeline, allowing the media to flow in one direction, to prevent accidents. This kind of valve should be installed horizontally in the pipeline. Swing check valve is suitable for nominal pressure PN1.0MPa~42.0MPa, Class150-2500; nominal diameter DN15~1200mm, NPS1/2~48; working temperature 196~540 degrees Celsius on the pipeline, to prevent the media back. Through the use of different materials (WCB, CF8 (M), CF3 (M), 1Gr5Mo, 15CrMo1V, can be applied to water, steam, oil, nitric acid, acetic acid, strong oxidizing medium and urea and other media. They are mainly used in petroleum, chemical, pharmaceutical, fertilizer, electricity and other pipelines.

Swing check valve with the built-in rocker swing structure, all opening and closing parts are arranged in the valve body of the valve, the valve does not penetrate, in addition to the seal gasket and seal ring with flange, overall no leak, to prevent leakage of the valve may be. Swing check valve rocker arm and disc connection with spherical structure, so that the valve flap in the range of 360 degrees have a certain degree of freedom, there is an appropriate micro position compensation.Suitable for clean medium, not suitable for containing solid particles and viscosity medium
