Actuator for modulating control

AME 445 - for industrial applications

Description

AME 445 actuator is used for industrial applications with two and three way valves type VRB, VRG, VF and VL up to DN 80 diameter.

The actuator has some special features:

•it automatically adapts its stroke to the valve end positions which reduces commissioning time (self stroking)

•valve flow adjustment feature; flow can be variably-adjusted from linear to logarithmic or opposite.

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

Combinations with other valves could be seen under Accessories.

Not appropriate for domestic applications, for hot water service with heat exchangers and for applications where higher noise level is not acceptable.

Main data:

•Nominal voltage (AC or DC):

•24 V, 50/60 Hz

•Control input signal:

•0(4)-20 mA

•0(2)-10 V

•Force: 400 N

•Stroke: 20 mm

•Speed: 3 s/mm

•Max. medium temperature: 130 °C

•Self stroking

•LED signalling

•External RESET button with lock option

•Output signal

•Manual operation

Installation

Mechanical

No tool is required 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 fixture. Once the actuator is placed, retighten the fixture.

Electrical

Electrical connections can be accessed by removing the actuator cover. Two cable gland entries without thread (Ø 16 and combined Ø 16/Ø 20) are prepared for cable glands. From factory one entry is provided by rubber cable gland and the other entry is prepared for opening.

Note:

Cable and cable gland used must not compromise the actuator’s

IP rating, and must ensure the connectors are fully strain relieved.

Rubber cable gland delivered from factory does not compromise

IP rating but it does not provide fully strain relieve according to

LVD directive.

Please observe local rules and regulations as well.
