M7410A

SMALL FLOATING LINEAR ACTUATORS

PRODUCT DATA

APPLICATION

The Honeywell M7410A actuators provide floating control of

specified VSOx series small linear valves.

They are suitable for use in room applications including

radiators, fan-coil units, and induction units, but also for zone

applications and small re-heaters. They are employed in

electronic temperature control systems with hot and/or cold

water as the controlled medium.

They are suitable for Honeywell Excel Series controllers as

well as for Honeywell individual room temperature controllers.

These controllers track the precise valve position by counting

the number of individual control pulses which move the valve

from one position to another. For this reason, the actuators do

not need end switches or a feedback potentiometer. The

absence of these mechanical components ensures long-term

reliability.

The M7410A actuators are also compatible with any controller

providing intelligent position control and having a built-in shut-

off function.

The M7410A actuators are well-suited for applications in

which space is limited and minimum power consumption is

required. They feature an attractive and rugged design.

FEATURES

Suitable for three-position floating control without

proportional feedback

Small size allows installation where space is limited

Low power consumption

Reliable long-term operation because mechanical

feedback potentiometers and mechanical end

switches are not required

Magnetic coupling for stem force limitation and self-

adjustment of the close-off point

Supplied with pre-wired connection cable

Simple, standardized M30 x 1,5 valve/actuator

coupling – no tools required for mounting

FUNCTION

The movement of the electric actuators is produced by a

screw spindle which is driven in both directions by a syn-

chronous motor through a set of gears. A magnetic clutch

limits the torque of the gear assembly and the driving force of

the actuators. The actuators are fixed to the valve body by

means of a coupling ring requiring no tools for mounting. The

actuators are maintenance-free and supplied completely with

a ready-to-wire connecting cable

MOUNTING POSITION

The actuator may be mounted only beside or above the valve.

Adjust the valve in the correct position before mounting the

actuator.

Fig. 2. Mounting positions

MOUNTING

Before the actuator is fixed to the valve, the adjustment cap

must be removed (see Fig. 3). Make sure that the actuator is

in the open position (factory-supplied position) before fixing

the actuator to the valve body.

Fig. 3. Removing the protection cap

The actuator must be mounted by hand. Do not use tools or

additional force insofar as this may damage the actuator and

valve.
