Original price was: £525.00.£400.00Current price is: £400.00.
Honeywell ML7420A6009 Actuator Valve – The drive of a synchronous motor is converted into linear motion of the actuator stem via a spur gear transmission. The actuator stem is connected to the valve stem via a button-keyed retainer. An integrated spring package limits the stem force to a factory-set value in either direction.

Description
The drive of a synchronous motor is converted into linear motion of the actuator stem via a spur gear transmission. The actuator stem is connected to the valve stem by a button-keyed retainer connection. An integrated spring package limits the stem force to a factory-set value in either direction. The actuator switches off precisely when the specified stem force is reached.
Actuators without spring return are equipped with a manual operation knob used in case of power failure. Manual operation is permitted only after the power supply is switched off or disconnected. To operate, push the manual operation knob down and turn clockwise to move the stem downward and counterclockwise to move the stem upward. If the actuator returns to automatic control, the manual operation knob unlocks automatically.
The direction of action can be reversed by pressing the lefthand pushbutton (W3) located on the printed circuit board (see Fig. 1), If the corresponding LED is lit, this indicates that the actuator stem will retract at a control signal of 0(2) Vdc (factory setting); if it is dark, the actuator stem will extend at a control signal of 0(2) Vdc.
