– DESCRIPTION –

Air actuated pvc ball valves are used for on-off control of water and other media compatible with the materials of construction. Spring return valves use air pressure to open the valve and springs (failsafe) to close the valve. Double acting valves use air to open and air to close the valve. Advantages of air actuated ball valves over other type valves may include: higher flow rates, higher pressures, wider media compatibility, straight through flow path, reduced water hammer, and use in hazardous environments.
