AVM 321S, 322S: Valve actuator
How energy efficiency is improved
Automatic adaptation to valve, optimal operator convenience, precision activation and high energy ef-
ficiency with minimal operating noise
Features
•
F
or actuation of 2- and 3-way valves
• For controllers with constant output (0...10 V / 4...20 mA) or switching output (2-point or 3-point con-
trol)
• BLDC motor (brushless DC) with SUT (Superior 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 display with bi-col-
our LED
• Automatic adaptation to the stroke of the valve, between 10 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 sig-
nal (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-Clorius valves
• Electrical parallel operation of five actuators
• Parameterisation option via the BUS interface
• Three-piece housing made of flame-retardant yellow/black plastic and seals with type of protection
IP54
• Maintenance-free gearbox made of plastic; threaded spindle and gearbox base-plates made of
steel
• Patented drive-valve coupling
• Mounting column made of aluminium
• Fixing bracket made of cast light alloy for valve fitting with 20 mm stroke and made of plastic for
valve fitting with 10 mm stroke
• Electrical connections (max. 1.5 mm²) with screw terminals
• Two break-out cable inlets for metric cable glands made of plastic M20 × 1.5
• Fitting position vertically upright to horizontal, not suspended
• Nominal thrust 1000 N

2)
Actuating power 1000 N under nominal conditions (24 V, 25 °C ambient temperature, 50 Hz). With boundary
conditions (19.2 V~ / 28.8 V~ / 21.6 V= / 28.8 V=, -10 °C / 55 °C, 60 Hz) and positioning time, the actuating/
ten-sile force is minimised to 800 N
3)
Noise level with the slowest positioning time, measuring distance 1m
