Check Valve

The cast iron lined rubber butterfly check valve produced by Tanggu Shengshi Huagong is a valve that is installed between two flanges by clamping and uses the valve disc to automatically open and close to prevent the backflow of the medium. The valve is based on cast iron and lined with rubber material inside. It has the high strength of cast iron and the corrosion and wear resistance of rubber. It is suitable for industrial pipeline systems that transport corrosive media. It is an important equipment to ensure the one-way flow of fluids and maintain the stable operation of the system.

The stainless steel clamp check valve produced and supplied by Tanggu Shengshi Huagong is a valve that relies on the flow of the medium and the deadweight of the valve disc to achieve one-way flow control through wafer-type installation between two flanges. Its unique wafer-type structure makes it small in size, light in weight, and compact in installation space. It can effectively prevent the backflow of the medium in the pipeline and is widely used in various industrial and civil pipeline systems. It is a key equipment to ensure the safety and stability of fluid transportation.

The cast steel silencing flange check valve produced by our Shengshi Huagong is a valve that integrates check and silencer functions. Through special structural design and material application, it can prevent the backflow of the medium while effectively reducing the noise and water hammer phenomenon caused by the fluid flow, ensuring the smooth operation of the pipeline system.

The cast steel swing flange check valve produced by Shengshi Huagong is an automatic valve that relies on the flow of the medium and the gravity of the valve disc to open and close by rotating the valve disc around the pin outside the valve seat. It is mainly used to prevent the backflow of the medium in the pipeline and ensure the safe and stable operation of the system. Its unique swing structure enables it to perform well in large-diameter pipelines and high-flow conditions, and is an indispensable fluid control equipment in industrial pipeline systems.

The cast steel lifting flange check valve manufactured by Shengshi Huagong is a valve that automatically opens and closes the valve disc by the flow of the medium itself to prevent the medium from flowing back. It belongs to the type of lifting check valve, and realizes the check function by the valve disc moving up and down along the axis of the valve seat channel. It is widely used in various industrial pipeline systems and is an important equipment to ensure the one-way flow of fluids and maintain the stable operation of the system.

The stainless steel swing check valve produced by Shengshi Huagong is a valve that automatically opens and closes the valve disc by the flow of the medium itself to prevent the medium from flowing back. It belongs to the automatic valve category. Its connection method adopts flange connection, which has the characteristics of convenient installation, strong sealing and wide application range. The main body of the product is made of high-quality stainless steel, such as 304, 316, etc., with excellent corrosion resistance, high strength and good heat resistance, can adapt to a variety of complex working conditions, and has a long service life.
