Product Description
Good Price Flanged DN40 Check Valves
Check valves serve to prevent the backflow of medium flow in the piping system, widely applied in the field of potable water, water supply and drainage, sewage disposal, irrigation, air conditioning, fire protection as well as chemical and energy industry.
Check valves are mechanical valves that allow flow in one direction and prevent backflow in the opposite direction. There are several types of check valves, each designed for specific applications and operating conditions. Some common types of check valves include:
1. Swing check valve: This type of check valve has a hinged disc that swings open to allow flow in one direction and closes to prevent backflow.
2. Lift check valve: Lift check valves have a disc that moves up and down to allow or prevent flow in one direction.
3. Ball check valve: Ball check valves use a ball or sphere to control flow, allowing the ball to move freely to open or close the valve.
4. Dual plate check valve: This type of check valve has two plates that open and close in response to flow, providing a tight seal to prevent backflow.
5. Wafer check valve: Wafer check valves are designed to fit between flanges and provide a compact and lightweight solution for preventing backflow.
