Pressure self sealing integral forging check valve

Overview and Application

Pressure self sealing integral forging check valveThe opening and closing components are opened or closed by the flow and force of the medium to prevent the medium from flowing back. Check valves belong to the category of automatic valves and are mainly used in pipelines where the medium flows in one direction. They only allow the medium to flow in one direction to prevent accidents.

① Self sealing check valves use self sealing as a high-pressure sealing technology. Under the premise that the pressure does not exceed the compressive strength of the pressure bearing parts, the higher the pressure, the better the sealing performance.

② Swing check valve, also known as swing check valve or swing check valve, is a type of check valve that opens or closes automatically by the flow of medium and gravity. Its function is to prevent the backflow of medium in the pipeline.

③ Swing check valves belong to the automatic valve category and are mainly used on pipelines with one-way flow of media. They are only allowed to be installed horizontally.

④ Suitable for clean media, not suitable for media containing solid particles and high viscosity.

⑤ The materials of the main body, internal components, gaskets, and fasteners can be reasonably combined according to user requirements or actual working conditions

⑥ Mainly used in pipelines for petroleum, chemical, pharmaceutical, fertilizer, electricity, and other industries.
