What it is

The ML7421A3004 is a Honeywell modulating linear valve actuator that drives a 20mm-stroke control valve using a 0-10V proportional control signal on a 24VAC supply, providing 1800N of linear force.

Signs this part needs replacing

  • Actuator fails to move, or the valve no longer modulates smoothly
  • Grinding, stalling or unusual noise from the actuator motor
  • Valve stuck fully open or fully closed, causing poor temperature control
  • No response to the 0-10V control signal from the BMS or controller

Before you order

  • Match the actuator to the exact valve series and stroke fitted to your system
  • Isolate the electrical supply before removing the old actuator
  • Confirm the control signal type (voltage or current) matches your controller
