Actuators for 3-point control

AMV 655 – without safety function AMV 658 SU, AMV 658 SD – with safety function (spring up/down)

Description

Actuators are primarily designed to control the valve in response to the demand of a controller in District Heating/cooling, Heating, Ventilating and Air conditioning systems.

Actuators AMV 655 and 658 can be controlled by electronic controllers with 3-point output.

Actuators can be used without any adapter in combination with:

- Valve types VFM, VFS (DN 65-100), VF (DN 100-150) and VL (DN 100)

- Self-acting flow controller AFQM 6 and AFQM*.

* With adapter 065B3527 for AFQM 6 or AFQM PN 25, if

produced be fore March 2015.

Used with adapter 065B3527 in combination with:

- Valve types VFG(S) and VFU.

Features:

• Manual operation mechanical and/or electrical

• Position indication, LED signalization

• Selectable speed 2 or 6 s/mm

• Integrated auxiliary switch

• External reset button

• 3-point control regulation

• Thermal and overload protection

• Precise control and fast response in 3-point mode (0.01 s)

Main data:

• Nominal voltage (ac or dc):

- 24 V, 50 Hz/60 Hz

- 230 V, 50 Hz/60 Hz

• Control input signal: 3-point

• Force: 2000 N

• Stroke: 50 mm

• Speed (selectable): 2 or 6 s/mm

• Max. medium temperature: depends on valve type. (from 150°C up till 300°C)

Mechanical

Please check the allowed installation positions for the valve and actuator. The actuator can be installed in all positions (see below).

<150 °C

Use a M8/SW13 key (not supplied) to fit the actuator to the valve body. Allow for necessary clearance for maintenance purposes. To link valve and actuator stems use a 4mm Allen key (not supplied). The actuator has position indication rings which should be pushed together before el. connection; after self-stroking they indicate end positions of the stroke.

Electrical connection

Electrical connections can be accessed by removing the service cover.

Four cable entries M 20×1.5 cable glands.

are provided for M 16×1.5 or

Note that in order to maintain the enclosure’s IP rating, appropriate cable glands must be used.
