Check Valve

Wafer Single Disc Swing Check Valves has short structure length, small size, light weight, fast closure of valve disc, small pressure of water hammer, convenient installation, small fluid resistance, sensitive movement, good sealing performance, short stroke and small impact force of the valve, the whole structure, simple compact, long service life, high reliability and so on.

The Wafer Lift Check Valves consists of valve body, disc and spring. It is installed horizontally or vertically in the pipeline system to prevent the media from backstreaming. The valve has the advantages of short structure, small volume, light weight, quick closing of disc, small water hammer pressure, smooth flow passage, small fluid resistance, sensitive action and good sealing performance.

Forged Swing Check Valves, also known as one-way valve, non-return valve and so on, is an automatic valve opening and closing itself by the force of flowing medium. And Forged check valve is mainly used for preventing the backflow of medium, the reversal of pump & its motor and the discharging of container. By different structure, it could be divided into forged swing type check valve & forged lift type check valve; If by different connection, it could be flanged forged check valve, socket welded forged check valve and etc.

Forged Piston Check Valves is a valve which is automatically opened and closed by the flow of the medium itself, and is used to prevent the reverse flow of the medium. It is also called a reverse check valve, a one-way valve, a countercurrent valve, and a back pressure valve. The check valve is an automatic valve. Its main function is to prevent the backflow of the medium, prevent the reversing of the pump and drive motor, and the discharge of the container medium. The check valve can also be used to supply pipelines where the pressure may exceed the system pressure. Check valves can be divided into swing check valves (with center of gravity rotation) and lift check valves (along the axis).

Flanged End Check Valves is used to prevent back flow in the line .Flow is in a straight line through the valve resulting in minimal pressure drop . The disc swings into the open position as the media flows through the line .Back pressure in the line holds the disc in the closed position . Flanged End Check Valves may be installed in horizontal or vertical lines ,but must be installed in proper relation to the media flow as indicated by the flow direction arrow marked on the body .

Forged Pressure Seal Swing Check Valves is a valve which is automatically opened and closed by the flow of the medium itself. It is used to prevent the reverse flow of the medium. It is also called the reverse check valve, the one-way valve, the countercurrent valve and the back pressure valve. The check valve is an automatic valve. Its main function is to prevent the backflow of the medium, prevent the reversing of the pump and drive motor, and the discharge of the container medium. The check valve can also be used to supply pipelines where the pressure may exceed the system pressure. Disc check valve around the pin inside the valve seat. The disc check valve is simple in structure and can only be installed on horizontal pipes with good tightness.

Forged Pressure Seal Piston Check Valves is a valve which is automatically opened and closed by the flow of the medium itself. It is used to prevent the reverse flow of the medium. It is also called the reverse check valve, the one-way valve, the countercurrent valve and the back pressure valve. The check valve is an automatic valve. Its main function is to prevent the backflow of the medium, prevent the reversing of the pump and drive motor, and the discharge of the container medium. The check valve can also be used to supply pipelines where the pressure may exceed the system pressure. The valve disc of the high pressure check valve is disc shaped and rotating around the seat channel. Because the valve channel is streamlined, the flow resistance is smaller than the butterfly check valve. It is suitable for large aperture with low flow velocity and unchangeable flow, but it is not suitable for pulsating flow and its sealing performance is not up to rise.

Y Type Piston Check Valves is, also known as one-way valve, non-return valve and so on, is an automatic valve opening and closing itself by the force of flowing medium. And Forged check valve is mainly used for preventing the backflow of medium, the reversal of pump & its motor and the discharging of container. By different structure, it could be divided into forged swing type check valve & forged lift type check valve; If by different connection, it could be flanged forged check valve, socket welded forged check valve and etc. The valve is used as boiler feed water and steam cut-off valve. It has integrated function of lift check valve and globe valve or angle valve.

The Non-slam nozzle check valves is a streamlined venture port design so as to reduce pressure loss. This series valve disc is the only moving part to minimize internal wear and compressed disc spring initiates valve closure as flow slows down and provides quick reaction on flow velocity change. It can be used in a wide range of critical and demanding services applications such as fast reversing reciprocating compressor system or installations where the check valve must be placed in close proximity to the pump inlet or outlet.

The Pressure Seal Tilting Disc Check Valve is a non impact check valve with flange size of ASME B16.5. Its main advantage is to overcome the impact and water hammer phenomenon of swing check valve and
