Forged steel check valve refers to a valve that automatically opens and closes the valve disc based on the flow of the medium itself, used to prevent medium backflow
Check valve is an automatic valve that mainly functions to prevent medium backflow, prevent pump and drive motor reversal, and prevent the discharge of container medium. Check valves can also be used on pipelines that provide supply to auxiliary systems whose pressure may rise above the system pressure.
Check valves can be mainly divided into swing check valves (rotating according to the center of gravity) and lift check valves (moving along the axis).
Swing check valves offer several features that make them advantageous in fluid control applications. Some key features include:
Swing check valves provide efficient fluid flow control, allowing for unidirectional flow and preventing backflow.
These valves have a minimal pressure decline through the valve, assuring effective discharge and lowering energy usage.
Swing check valves are relatively easy to maintain, as they have a simple design with fewer moving pieces.
Swing check valves can handle a broad range of fluids, including liquids, gases, and slurries. They find applications in various industries, such as water treatment, oil and gas, chemical processing, and more.
