Check valve(non-return valve) refers to a valve whose opening and closing parts are circular discs and rely on its own weight and medium pressure to generate actions to block the back flow of the medium. Available in swing check valve/spring check valve/flap check valve for your choice. Also available in stainless steel, brass and WCB material to meet your standard.
Types Of Check Valve For Your Choice:
Swing Check Valve
Swing Wafer Check Valve
Spring Check Valve
Swing Check Valve:
Swing check valve available in ANSI, JIS, DIN, GB standard for your choice. Available in WCB, stainless steel material to meet the medium requirements. Offering connection solution for the application which needs flange connection. It can effectively prevent the medium from flowing back and protect the safe operation of the equipment.
Swing Wafer Check Valve:
When the medium enters the check valve according to the normal inflow direction, the pressure of the medium will reopen the valve disc and flow through the valve. But when the medium flows back, the disc will be pushed back to prevent the back flow.
Available in WCB and stainless steel material.
Spring Check Valve:
There is a spring inside. When the medium circulates in the normal flow direction, the pressure of the medium will compress the spring, thereby opening the valve flap for circulation. When the pressure gradually decreases, the spring will drive the valve flap to slowly close, thereby preventing the medium from flowing back. Good sealing performance.
Available in brass and stainless steel material.
