Professional Manufacturer of Non-return Sanitary Spring Check Valves
Application:
These check valves are designed for stainless steel pipeline systems to prevent fluid from flowing backward.
Working Principle:
The check valve operates based on the flow of the medium itself. The valve disc opens when the pressure below the stem exceeds the pressure above it. Conversely, the valve disc closes when the pressures equalize, ensuring the fluid flows in one direction and preventing backflow, thereby avoiding potential accidents.
Standard Design:
We offer a variety of check valves adhering to standards such as DIN, 3A, SMS, ISO/IDF, BS/RJ, RJT, and more, tailored to client requirements.
