Valve actuator
AVM 321S, 322S
How energy efficiency is improved
Automatic adaptation to valve, optimal operator convenience, precision activation and high energy efficiency with minimal operating noise
Features
-
In ventilation air conditioning units for actuating 2- and 3-way valves of type series AVM 321S: VUD, VUE, VUN, BUD, BUE, BUN and AVM 322S: V6R, VQD, VQE, VUG, VUP, VUS, B6R, BQD, BQE, BUG, BUS
-
For controllers with constant output (0…10 V / 4…20 mA) or switching output (2-point or 3-point control)
-
BLDC motor (brushless DC) with SUT (SAUTER Universal Technology) electronic control unit of the third generation and electronic load-dependent cut-off
-
Automatic detection of applied control signal (continuous or switching), operating indicator using bi-colour LED
-
Automatic adaptation to the stroke of the valve, between 8 and 20 mm
-
Low operating noise
-
With the built-in absolute distance measurement system, the position is always maintained in the case of power failure
-
The direction of operation, characteristic (linear/equal percentage), positioning time and control signal (voltage/current) can be adjusted via coding switches
-
Integrated forced operation can be set via coding switches (with selectable direction of operation)
-
Easy re-initialisation using a coding switch
-
Crank handle for external manual adjustment with motor cut-off
-
Simple assembly with valve; spindle is automatically connected after control voltage is applied
-
Numerous adapters enable the unit to be fitted onto non-SAUTER valves
-
Electrical parallel operation of five actuators
-
Parameterisation option via the BUS interface
