Check valves are essential components in piping systems that ensure fluid flows in a single direction, preventing backflow and potential damage. This high-pressure spring-loaded check valve is designed with a stainless steel body and PTFE seals, offering excellent resistance to corrosion and wear. It can be used with a wide range of media including water, oil, gas, air, light alkalis, acids, biodiesel, fuels, and alcohols.
These check valves are ideal for industrial and commercial applications where reliable flow control is required. The swing design allows the disc to open when the flow is in the correct direction and close automatically when the flow reverses. However, it's important to note that swing check valves are only suitable for horizontal installations. Vertical use may interfere with the proper operation due to gravity affecting the swinging motion.
The product meets international standards such as ANSI B16.34 and DIN, ensuring compatibility and performance across different systems. It is available in various sizes from 1/4" to 4", and the threaded ends conform to multiple global standards like ANSI, DIN, and JIS.
