SHANDONG PIPESOL FLOW EQUIPMENT CO.,LTD
Check valves are "automatic" valves that open with forward flow and close with reverse flow. The pressure of the fluid passing through a system opens the Valve, while any reversal of flow will close the valve. Our range included swing check valves, wafer check valves.
Swing check valves come with resilient seats. Installed in pumping applications to prevent back flow they can be used for drinking water as well as waste water. The disc is connected to the shaft via a flexible bush that allows disc and valve seat to adjust exactly. All interior parts are ductile iron coated with drinking water approved epoxy or EPDM.
