Forged Steel Electric Actuator Trunnion Mounted Ball Valve Big Size
Description
The thrust bearing reduces the friction torque of the valve stem and enables the smooth and flexible operation
of the valve stem for a long time. The valve seat sealing performance is good, the structure is easy to seal,
and the sealing ability of forged steel ball valve increases with the increase of medium pressure.
