Cause
Replacement actuator for a STL-SR valve
Resolution
A M800 actuator or MV15B-24 or MV15B-230 actuator can be used to replace the actuator on the STL-SR valve series. Click here for the STL-SR datasheet.
Notes:
The original actuator e.g. M5CP, may have had a potentiometer fitted to provide position feedback to the controller. There is no direct replacement, the controller, actuator and valve may have to be changed. As a workaround, The M800 provides a 2-10V feedback, using a signal conditioner this could be converted to a resistive feedback.
The original actuator may have had end switches fitted, order end switches to suit the replacement actuator.
The M800 when used in floating control mode (dip switch 2= On) requires 4 wires. The original actuator used 3 wires to provide floating control.
