Valworx 553502A air actuated double acting stainless steel ball valves are typically used for on-off control of air, water, oil, and other media compatible with the materials of construction. Double acting actuators use air pilot pressure to open and air pilot pressure to close. High temperature valve mounting kit available for extended temperature range or wall mounting applications. Advantages of air actuated ball valves over other type valves may include: higher flow rates, higher pressures, higher temperatures, wider media compatibility, straight through flow path, reduced water hammer, and use in hazardous environments. Ball valve can be mounted in any orientation.
