Swing Check Valve
Swing Wafer Check Valve
Spring 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.
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.
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.
