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.
