SAUTER AVF234SF232 Linear valve actuator AVM 234S series

AVM321SF132    Linear Valve Actuator

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

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 thrust 1000 N

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 running time, the actuating/tensile

force is minimised to 800 N
