Valworx 552508A air actuated spring return stainless steel ball valves are typically used for on-off control of air, water, oil, and other media compatible with the materials of construction. Unique three piece investment cast bolted body design offers the advantage of a swing out body for easy inline maintenance. Spring return actuators use an air pressure signal (58- 87 PSI) to open and springs to close the valve. The valve will fail closed upon loss of air signal. 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.
