Johnson Controls D-3031 Pneumatic Piston Damper Actuator

Pneumatic Piston Damper Actuator
D-3031

The D-3031 Pneumatic Actuator is designed primarily for damper positioning on small terminal units. Models, furnished with 1 inch (25 mm) stroke, have two movable adjustment stops to facilitate adjusting the stroke in 1/8 inch increments. The D-3031 features a polycarbonate top and body and a threaded 5/16 inch (8 mm) diameter piston rod for convenient linkage attachment. The D-3031 is the unit replacement for D-160 and D-251 #2S actuators.

• high power to size ratio for locations in confined spaces
• swivel or rigid mounting options for flexible mounting configurations
• optional mounting kits to cover any application and replacement of obsolete units
• barbed fitting for 5/32 inch or 1/4 inch O.D. tubing
