JOHNSON CONTROLS Pneumatic Damper Actuators

Johnson Controls pneumatic valve actuators are used to position hot-water, chilled-water and steam-control valves using a pneumatic signal from a controller. These actuators have a moulded, synthetic diaphragm that provides sufficient area throughout the actuator stroke and is enclosed in a sturdy, corrosion-resistant housing. These Johnson Controls valve actuators meet ASME standards and have a position indicator for visual indication of the valve stem position.
