AVM 321S, 322S Valve Actuator

Automatic adaptation to valve, optimal operator convenience, precision activation and high energy efficiency with minimal operating noise

Features

• In ventilation and 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 bicolour LED
• Automatic adaptation to the stroke of the valve, between 8 and 20mm
• 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), running 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
• 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 actuator-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 8 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 vertically upright to horizontal, not suspended
• Nominal actuating power 1000N
