Valworx 545704 pneumatic/manual 3-way lead free brass ball valves are designed for use with air, water, oil, and other media compatible with the materials of construction. The de-clutch option can be used for manual operation or to set a limit stop for opening or closing. These T-port ball valves can be used as a diverter, selector or mixing valve. Ideal where lead free and NSF approved construction are required for potable drinking water as well as other industrial applications. Double acting actuators use an air pressure signal (58- 87 PSI) to change the valve to position 1 or position 2. There is no flow shutoff position with this type valve. Actuator has standard ISO/Namur interface for mounting optional direct mount solenoid valve and other accessories. These actuated ball valves can be mounted in any orientation. Suitable for steam up to 50 PSI max. with kit and vacuum service to 29 inch Hg.
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.
