Unox Stainless Steel Disc Check Valve

What is a Stainless Steel Disc Check Valve?

A stainless steel disc check valve is a type of valve that allows fluid to flow in only one direction, preventing backflow. It consists of a valve body with a hinged flap or disc attached. When the fluid flows in the correct direction, the disc moves out of the way, allowing the fluid to pass through the valve. When the flow stops or reverses, the disc returns to its original position, preventing fluid from flowing backward.

Stainless steel is commonly used in check valve construction because it is corrosion-resistant. Check valves are widely used in various applications, including water treatment plants, chemical processing facilities, and oil and gas pipelines, to prevent backflow and protect equipment and piping from damage.

Check valves are general-purpose fittings suitable for liquids, gases, and steam. They enhance operational safety and can sometimes replace more complex fittings. Using such a valve is advantageous because it requires minimal installation space and time, saving floor area—making the Unox Disc Check Valve especially practical.
