Swing Check Valve is also known as one-way valve or check valve. Its function is to prevent the medium in the pipeline from flowing back. It is mainly used in the pipeline where the medium flows in one direction. It only allows the medium to flow in one direction to prevent accidents. The Swing Check Valve produced by Milestone Valve Company is designed and manufactured in strict accordance with the GB12236 standard. The pin and valve disc link adopts a built-in structure with excellent performance and reliable sealing. It is widely used in various pipelines in the petroleum, chemical, pharmaceutical, and electric power industries.

1) Swing Check Valve products are designed and manufactured according to GB12236 design standard, with reasonable structure, reliable sealing and beautiful appearance;
2) The sealing surface of Swing Check Valve disc and valve seat is made of stellite cobalt-based hard alloy surfacing, which has good wear resistance, high temperature resistance, scratch resistance and long service life;
3) Swing Check Valve can adopt various piping flange standards and flange sealing surface types to meet various engineering needs and user needs
4) Swing Check Valve has a complete range of materials for the valve body. Packings and gaskets are reasonably selected according to actual working conditions or the user's spirit, which can adapt to various pressure, temperature and medium working conditions.
5) Swing Check Valve disc rotates around the pin shaft outside the valve seat to reduce violent conflicts when closing;
6) Swing Check Valve pin shaft and valve clack are connected with a built-in pin shaft structure, which reduces external leakage points and is more reliable in use.
7) The Swing Check Valve disc rotates around the shaft, and its fluid resistance is generally less than that of the lift check valve. The installation position is not restricted. It is usually installed with horizontal pipelines, suitable for larger diameter occasions; It can be divided into three types: single-petal swing type, double-petal swing type and multi-petal swing type;
