Description
The Schimpf Servo drive 02-25/4500 (SKU 1320808) is an actuator for industrial heating systems, designed to position air dampers or mixing valves. It operates on a 230 V supply, delivers a torque of 40 Nm, and completes a 90° rotation in 60 seconds. This model supersedes the older 02-20/430 and is compatible with Ammann and Schimpf burners. Its type designation is 862.712.013.
Further details
| Failure modes | stripped gear trains, failed end switches, or a seized valve stem after prolonged standstill |
|---|---|
| Function | translate a control signal into rotational movement to position air dampers or mixing valves |
| Product group | actuators used in industrial heating systems |
| Replacement checks | verify that the control signal from the burner or system controller matches the drive's input. also check the mounting interface and coupling dimensions, as well as the angle of rotation and auxiliary switch configuration if used for end-position feedback |
| Selection criteria general | the same selection criteria apply regardless of the specific model number, so ensure these parameters are confirmed against the original unit before installation |
Choosing and fitting
When selecting a replacement actuator of this type, verify that the supply voltage, torque, runtime, and rotation angle match the original unit. Check the control signal format (e.g., three-point, 0-10 V, or on/off) and ensure the mounting interface and coupling dimensions are compatible. Also confirm the angle of rotation and whether auxiliary switches are needed for end-position feedback.
Signs of failure
Common failure modes include stripped gear trains, failed end switches, or a seized valve stem after prolonged standstill. Symptoms may include the actuator not moving, moving partially, or making unusual noises. Check for proper control signal input and inspect the mechanical linkage for binding or wear.
