Forged Check Valve
A Forged Steel Check Valve refers to a valve that automatically opens and closes the valve disc by means of the flow of the medium itself, and is used to prevent the back flow of the medium, also called a clack valve, non-return valve, one-way valve or reflux valve. A check valve is an automatic valve whose main function is to prevent backflow of the medium, prevent the pump and drive motor from reversing, and discharge the container medium. Forged steel check valves can also be used in supply pipeline for an auxiliary system in which the pressure may rise to or exceed the system pressure. They can be mainly divided into a swing type check valve (rotation according to the center of gravity) and lift type check valve (moving along the axis).
For medium and low pressure check valves with DN50mm or less, the body and bonnet should be bolted, that is, a Bolted Cover Forged Check Valve should be used.
For high-pressure forged steel check valves under DN50mm, the pressure self-sealing type (Pressure Sealed Bonnet Forged Check Valves) should be selected.
For medium and high pressure forged steel check valves with DN50mm or less, Welded Cover Forged Check Valves should be used.
