The Piston Type Flow Regulating Valve reciprocates in the direction of the centerline of the pipeline through the piston in the valve to increase or decrease the cross-sectional area of the outlet to adjust the flow rate.

There are four types of valve outlets: E type is suitable for throttling, F type is suitable for opening and closing, and S and L types are suitable for adjustment. The electric type can be made into an automatic adjustment type to adjust the media parameters in the pipeline.
