Schneider Electric Pneumatic Valve Actuator

The Schneider Electric (Barber Colman) Pneumatic Valve Actuator line provides proportional pneumatic control of hot water and chilled water globe valves in commercial and industrial HVAC systems. These diaphragm-type valve actuators are also called pneumatic globe valve actuators. They convert a branch-line air signal into linear stem movement. That movement positions the valve for accurate temperature control.

Key Features:

• Pneumatic diaphragm design for proportional control, with 2-position operation also supported
• Built-in spring that retracts the output shaft and raises the valve stem when air pressure is lost
• Adjustable start point
• Replaceable beaded molded neoprene diaphragm
• Die-cast aluminum housing
• Linear mechanical movement
• 1/8 in. NPT air connection
• NEMA Type 1 enclosure rating
• Designed for use with Schneider Electric VB-series globe valves
• Operating ambient temperature range of -20 to 220 °F

Valve linkage and optional positive positioners are ordered separately. Models in the line differ in diaphragm area and spring range, so choose the variant that matches your valve and control signal. The line suits air handling units, fan coil units and other HVAC equipment that needs dependable, repeatable valve positioning.
