Introduction for forged steel check valve

Forged steel check valve is mean the material are the forging(not cast steel),the material can be forging or casting for all of the check valves,the forged steel check valve also have two type, one is swing type and anther is lift type,the highest pressure for forged steel check valve can up to 2500LB(PN420), the body of the check valve are forged material ,this valve is opened or closed by the valve disc to rotate around the spindle outside the seat of the valves;  it is an automatic valve, working principle of this valves are automatically opened or closed by the force generated by the medium flowing within the pipeline. Its major function is to prevent the backflow of the medium in the pipeline, reverse rotation of the pump and its driving motor, and discharge of the medium in the container.


Features for forged steel check valve

Compact and reasonable product structure, reliable tightness and good performance;

Smooth fluid passageway and small fluid resistance;

Swing type disc or lift type disc.

Can be designed with a Damping Cylinder.

Rapid closing and flexible actions of the valve disc .

Small closing impact, water hammer is not liable to be generated.

Smooth fluid passageway and small fluid resistance.
