Electro-mechanical actuator for the control of two-way and three-way plug valves

Advertisement

Quick Links

M400 is an electro-mechanical actuator for the control of
two-way and three-way plug valves in:
heating systems
air handling systems
M400 is primarily designed for applications where the
demands on actuator speed and thrust are small.
The actuator can not be equipped with Self Testing
Device STS.
M400 is either controlled by an increase/decrease signal
or by a modulating 0–10 V control signal.
The electronic circuitry of the actuator ensures that the
running time is the same, regardless of the stroke of the
valve in question.
It is easy to mount and connect the actuator. It can be
mounted directly onto TAC's control valves, without any
mounting kit.
For Satchwell valves a linkage is included (see PART
NUMBERS on page 2)
The working range of the actuator is adjusted
automatically depending on the stroke of the valve. The
electronic circuitry of the actuator then takes care of the
adjustment of the valve end positions.
The actuator is supplied by 24 V AC. It can provide a
position indicator signal 2-10 V and a 16 V DC voltage
supply for older TAC controllers.

  • Page 3 MOUNTING The actuator may be mounted horizontally, vertically and in any position in between, but not upside down, see figure 3. N.B.! Do not use the actuator for the DN15 valves V298, V282, V294, V384, V386 and V394. To mount the actuator on a valve, slide the actuator onto the valve neck, thus making the square nut on the valve spindle fit into the groove on the cross...
