304/316L Stainless Steel Sanitary Check Valve Welded End. Our Check Valves are designed to prevent reverse flow.Concentric and eccentric styles as well as our tapered disk design are available for horizontal,vertical applications and are working well without leaking while getting a returnpressure.Our special designed Check valve can be using for many applications in such as food, dairy, beverage,pharmaceutical, chemical, and many other industries.
Application:
A check valve, also called a one-way valve, is a device that allows the flowof fluids to move only in one direction.
Work Principle:
The working principle of the check valve is to allow one-way flow andautomatically prevent reverse flow. This type of valve is sensitive to flowand relies on the medium to open and close the valve seat. The inner discallows the medium to flow forward, thereby forcing the valve to open.
Technical Data:
If the check valve is installed in a vertical pipe, the pressure required toopen the valve is about 6 KPA, the maximum conveying material pressureis 1000 KPA, the operating temperature range is-10 °C-140 °C.
Material:
Steel parts: 304 stainless steel, stainless steel 3161.Seal: VMP.FPM,EPDM
Mark Design:
There are a variety standards of check valves available, namely for DinStandard Series, 3A standard series, SMS Standard Series, ISO/IDFstandard series, BS/RJT standard series, ASME/BPE standard series.
The body of the check valve is divided into two parts, which areassembled by clamps and sealed with a special gasket. A guide discand four guide rods guide the spring witi an o-ring spool. The checkvalve has welded, clamp and male thread connections, suitable for avariety of pipe connections.
