Sanitary Check Valve

Xusheng(Sanicompass)'s Sanitary check valves of operation principle, the valve opens when the pressure of the fluid exceeds the pressure exerted by the pump spring. When the two pressures are equalised, the valve closes. A stronger counter- pressure allows the valve to close. At the same time, our valves have welding, clamp, thread, union, and other connection methods, and meet DIN, SMS, RJT, ISO, IDF, 3A and other standards. And our sealing ring can also have a variety of options,The material of gasket contains Silicone, EPDM, NBR or FKM, Which all confirm to standard of FDA 177.2600. Working temperature: -10℃/+120℃. The Max pressure of valve is 10BAR.

Xusheng(Sanicompass) can produce sanitary check valves as per customers' design drawing and requirement.


  • Sanitary Stainless Steel Clamp Type Thread Check Valve
    Sanitary Stainless Steel Clamp Type Thread Check Valve
    Sanitary check valve, also known as "non-return valve", is designed for use in process piping installations to prevent reverse flow. VCN series is a spring check valve with different connection ends.
    A check valve opens when the pressure below the valve plug exceeds the pressure above the valve plug and the spring force. The valve close when pressure equalization has been achieved.
