Actuators for three point control
AMV 25 SD - safety function (spring down)
AMV 25 SU - safety function (spring up)
Description
AMV 25 SD or SU electric actuators are used
with valves gen.2009 type VRB, VRG, VF, VL with
additional adapter (Code No. 065Z0311, not
supplied) and VFS 2 valves up to DN 50 diameter.
The actuator automatically adapts its
stroke to valve end positions which reduces
commissioning time. Optional auxiliary switches,
feedback potentiometer and valve stem heater
are available.
The actuator has some special features:
• The advanced design incorporates load
related 'switch-off' to ensure that actuators
and valves are not exposed to overload;
• Digitale feedback end position indication
signal for valve end position is available by
terminal 4 or 5;
• Low weight and robust;
• Safety function versions:
- SD (spring down)
- SU (spring up).
Main data:
• Nominal voltage:
- 24 VAC, 50 Hz/60 Hz
- 230 VAC, 50 Hz/60 Hz
• Control input signal:
3 point
• Force: 450 N
• Stroke: 15 mm
• Speed: 15 s /mm
• Max. medium temperature: 15 0 °C
• End-position signals

The safety function will fully open or close the
valve by power failure, depending upon the
chosen safety action (SD/SU).
Valve selection will also affect the safety action.

The safety function unit is factory fitted to the
rear of the actuator.

Mechanical
Use 4 mm Allan key (not part of actuator
delivery) to mount actuator on the valve.
Installation of the valve with the actuator is
allowed in horizontal position or upwards.
Installation downwards is not allowed.
The actuator must not be installed in an
explosive atmosphere, at ambient temperature
lower than 0 °C or at ambient temperature higher
than 55 °C. It must not be subject to steam jets,
water jets or dripping liquid as well.

Electrical
Electrical connections can be accessed by
removing the actuator cover. Two cable gland
entries with thread (M20 x 1.5 and M16 x 1.5) are
prepared for cable glands.
Note: Cable and cable gland used must not
compromise the actuator’s IP rating, and must
ensure the connectors are fully strain relieved.
Please observe local rules and regulations as well.
Note: the actuator may be rotated up to 360° with
respect to the valve stem by loosening the retaining
fixture. Once the actuator is placed, retighten the
fixture.

before the power supply is fully
switched off.
Terminals 1, 3:
Control voltage input from the controller.
Terminals 4, 5:
Output used for position indication or
monitoring.

Commissioning
Manual override
Complete the mechanical and electrical
installation and perform the necessary checks
and tests:
- Turn on the power.
- Set the appropriate control signal and check
that the valve stem direction is correct for the
application.
The unit is now fully commissioned.

AMV 25SU
5mm
Manual override is done by means of positioning
spindle inside the actuator:
• Disconnect power signal
• Remove the actuator cover
• Insert 5 mm Allan key (not part of actuator
delivery) into the top of the positioning spindle
• Turn the key against the spring (observe the
rotation direction)
To hold a manual override position, the key must
be wedged.
After manual override is not needed:
• Restore power signal.
