Check Valves Manufacturers in USA

Industrial check valves are designed to allow fluid to flow through in only one direction, preventing backflow or reverse flow. They are commonly used to protect sensitive equipment such as pumps, compressors, and hydraulic systems from damage caused by backflow.

The types of industrial check valves include:

1. Swing Check Valve: This type of valve has a hinged disc that opens when the fluid flows in one direction but closes when there is backflow. It is commonly used in low-pressure applications.
2. Ball Check Valve: This type of valve uses a ball to block the flow when there is backflow. The ball is held in place by a spring, and when the flow is in the correct direction, the ball moves aside and allows the fluid to flow through.
3. Diaphragm Check Valve: This valve has a flexible diaphragm that moves up and down to allow the flow in one direction but blocks it in the other direction.
4. Lift Check Valve: This valve operates based on fluid pressure, with the flow moving up to lift the disc and allow the flow in one direction. When the flow stops, the disc falls back into place to prevent backflow.

Industrial check valves are made of various materials such as stainless steel, bronze, cast iron, and plastic. The choice of material depends on the type of fluid, pressure, and temperature being used. They can be found in industries such as petroleum, chemical, pharmaceuticals, and water treatment plants.
