The D-3031 replaces the unit replacement for the D-160 and D-251 #2S actuators.
Installation
The D-3031 is designed for to operate normally open or normally closed dampers using either swivel (Figure 3) or rigid (Figure 4) type face mounting. The actuator can be rotated to locate the air connection in the preferred position.
Features
- 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 in. or 1/4 in. Outside Diameter (O.D.) tubing
Applications
The D-3031 has a maximum stroke of 1 in. without stops. Two stroke adjustment stops are provided for limiting the stroke in 1/8 in. increments from 7/8 to 1/2 in. When the stop is properly seated in the stroke adjustment window, its elongated section should face the hub end of the actuator and rest against the inside wall of the body (Figure 5).
