The Honeywell VMM actuator is designed to provide floating
control in heating and air conditioning systems. High control
performance and a robust design are standard. In combination with the valves DR/ZR/DRU, it is possible to control
very exact heating and cooling water temperatures. The
mechanical interface between actuator and valve is designed
for reliable operation. Actuators with torques from 20 Nm up
to 40 Nm are available for a wide range of rotary mixing
valves (DN 15…200).

Attention (VMM40-24F)
Higher temperatures (>50 °C) combined with the min. voltage
(19.2 Vac) could reduce the output torque by approx. 10%.
Higher temperatures (>60 °C) combined with the max. voltage
(28.8 Vac) allow only three full strokes to be carried out
without interruption.

Mounting on the Valve
Before mounting the actuator, position the rotary valve
according to its installation instruction. In the case of boiler
applications, it is recommended that the actuator be mounted
in a vertical position. If mounted in the horizontal position, one
should position an isolation shield between the top of the
valve and the actuator; this is to protect it against radiant heat
and to ensure ambient temperatures of below 60 °C.
Operation
The actuator is powered by a synchronous motor. The spindle
of the actuator rotates 90°. In the end positions, the motor is
switched off by end switches.
Manual operation declutches the gear from the valve. As soon
as the actuator is powered, the valve is driven by the actuator
again.
No adjustment necessary. The actuator is maintenance-free.
