Product Description

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:

Effective Flow Control

Swing check valves provide efficient fluid flow control, allowing for unidirectional flow and preventing backflow.

Low-Pressure Drop

These valves have a minimal pressure decline through the valve, assuring effective discharge and lowering energy usage.

Easy Maintenance

Swing check valves are relatively easy to maintain, as they have a simple design with fewer moving pieces.

Versatility 

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.
 

Swing check valves operate based on the principle of the swinging disc, which moves freely to allow or block the flow of fluids. When the fluid flows in the desired direction, the pressure pushes the disc open, allowing the fluid to pass through. However, when there is a backflow or a reverse flow, the disc swings back into position, creating a seal and stemming the fluid from flowing in the opposite direction.






In pipes and similar devices and equipment, check valves are generally used to prevent a reverse flow by allowing materials or fluids to flow in only one direction. Despite their various forms, sizes, and functions, these valves generally operate based on the same principle. 

The primary components of a check valve include the Body,Body Seats,Gasket,Cover Plate,Hinge,Nuts,Washer.
