API CAST STEEL PRESSURE SEAL SWING CHECK VALVE
Cl900, 1500,2500Lb

MAIN FEATURES:

The valve is opened or closed by the valve disc to rotate around the spindle outside the valve seat;

and it is an automatic valve when it is 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.
