Check Valve Manufacturers & Suppliers

Check valves are mechanical devices that allow fluid to flow in only one direction. They are used in a variety of industries, including oil and gas, water treatment, and pulp and paper. Check valves are typically installed at the end of a pipeline or pump to prevent backflow. Industrial check valves are available in a variety of materials, including cast iron, steel, bronze, and plastic. Each material has advantages and disadvantages that should be considered when selecting a check valve for a particular application. Check valves are an essential component of many industrial systems and play an important role in preventing backflow and pipe damage.

Check valves are one of the most important types of valves used in many industries today. Check valves allow fluid to flow in only one direction and are therefore used in a wide variety of applications where backflow needs to be prevented. Check valves are classified according to how they operate; the most common types are lift check valves, swing check valves, and ball check valves. Lift check valves have a disc that opens when fluid flows in the correct direction and closes when fluid tries to flow backwards. Swing check valves have a hinged disc that swings open when fluid flows in the correct direction and closes when fluid tries to flow backwards. Ball check valves have a ball that fits snugly into a seat; when fluid flows in the correct direction, the ball is pushed out of the way and allows fluid to pass through, but when fluid tries to flow backwards, the ball seals off the seat and prevents backflow. Check valves are used in myriad applications across many industries, making them some of the most popular valve types today.
