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.
