Valworx 543904A stainless steel full port three way ball valves are designed for use with water, air, oil, and other media compatible with the materials of construction. This diverter valve has a T-port flow pattern. There is no flow shutoff position with this type valve. Double acting actuators use an air pressure signal (58-87PSI) to change the valve to position 1 or position 2. 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. Valve is tested per API 598, can be mounted in any orientation.
