Design Details: The Pressure Balanced System ensures line pressure acts on the plug to reduce the valve torque and avoid the possibility of plug seizure, even after a prolonged time in the open or closed position. Periodic lubricant injection, and seat adjustment, can be carried out when the Plug Valve is under full pressure. Only severe seat damage will cause a reduction of valve sealing. No spare parts are required and bubble tightness is guaranteed in critical service.
