Actuator for three point control AMV 438 SU – safety function (spring up)

Description

AMV 438 SU actuator is used with two and three-way valves type VRB, VRG, VF and VL up to DN 50 diameter.

Ordering Actuator

Typ e Supply voltage Code No.

AMV 438 SU

24 VAC 082H 0122

230 VAC 082H0123

The actuator has some special features:

• advanced design incorporates load related ‘switch-o’ to ensure that actuators and valves are not exposed to overload

• Safety function (spring up): In case of power failure or power switch o spring up function retracks actuator stem to end position. Further manual stem positioning is not disabled.

Installation 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.

Note: the actuator may be rotated up to 360° with respect to the valve stem by loosening the retaining xture. Once the actuator is placed, retighten the xture.

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.

Disposal The actuator must be dismantled and the

elements sorted into various material groups before disposal.

Wiring

230 VAC version:

Do not touch anything on the PCB! Do not remove the cover before the power supply is fully switched o.

Accessories

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.
