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
servi ce with heat exc hangers and f or applicati ons where
higher noise level is not acceptable.
Main data:

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

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 actuato r may be rotated up to 360° with respe ct to the valve
stem by looseni ng the retaining fixtur e. 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 g land used must not compromise the a ctuator’s
IP rating, and must e nsure the connectors are ful ly strain relieved.
Rubber cabl e gland delivered from fac tory does not compromis e
IP rating but it doe s not provide fully strain rel ieve according to
LVD directive.
Please obser ve local rules and regulatio ns as well.

Jumper/DIP switch setting
Jumper
• U/I - Input signal type selector
• U position; voltage input is selected
• I position; current input is selected
DIP switches
• SW 1: Not used
• SW 2: Input signal range selector
• OFF position; the input signal is in the range
from 0-10 V (voltage input) or from 0-20 mA
(current input)
• ON position; the input signal is in the range
from 2-10 V (voltage input) or from 4-20 mA
(current input)
• SW 3: Direct or inverse acting selector
• OFF position; the actuator is in direct acting
mode (stem extend as voltage increases)
• ON position; the actuator is in inverse acting
mode (stem retracts as voltage increases)
• SW 4: Not used
• SW 5: Not used
• SW 6: Not used

• SW 7: Linear or equal-percentage flow
through valve selector
• OFF position; the valve position is linear acc.
to the control signal
• ON position; the valve position is equalpercentage acc. to the control signal. This
relation is adjustable - see Equal-percentage
valve-flow adjustment section
• SW 8: Smart function selector
• OFF position; the actuator does not try to
detect oscillations in the system
• ON position; the actuator enables special anti
oscillations algorithm – see Anti oscillations
algorithm section
Equal-percentage valve-flow adjustment
(SW 7 in position ON)
The actuator has a special valve-flow
adjustment feature. Flow can be, by turning
the potentiometer clock wise (CW) or counter
clockwise (CCW), variably adjusted from linear
to logarithmic or opposite. For details see
Instructions.
