3/8" Air Actuated Brass Ball Valve - Spring Return

Valworx 521441 air actuated lead free brass ball valves are used for on-off control of air, water, oil, and other media compatible with the materials of construction. Ideal where lead free and NSF approved construction are required for potable drinking water as well as other industrial applications. Spring return actuators use an air pressure signal (80-120 PSI) to open and springs to close the valve. The valve will fail closed upon loss of air signal. 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. 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.
