| AVM 234S: Valve drive with SUT positioner
How energy efficiency is improved
Automatic adaptation to valve, precision control and high energy efficiency with minimal operating noise.
Areas of application
Actuation of through or three-way valves in the V/BUD and V/BUE DN65 - 150 series, as well as V/BUG, V/BUS, VUP and V/B6R DN15 - 150. For controllers with continuous output (0 - 10 V or 4 - 20 mA) or switching output (2-point or 3-point control).
Properties
- Pushing force of minimum 2500 N
- Stepping motor with SUT (Sauter Universal Technology) electronic control unit and electronic load-dependent cut-off
- Automatic detection of control signal applied (continuous or switching), display via 2 LEDs
- The type of characteristic curve (linear, quadratic or equal percentage) can be adjusted in the drive
- Independent adaptation to valve stroke between 8 and 49 mm, captive even if the power is turned off
- Direction of travel can be selected via screw terminals when making electrical connection or remotely
- Coding switch for selection of characteristic and running time (35, 60 or 120 sec.)
- Hand crank for external manual adjustment with motor cut-off and as trip for re-initialisation
- Easy assembly with valve, spindle connection takes place automatically after application of control voltage
- Many adaptors allow assembly on third-party valves
Technical description
- Power supply 230 V with modules or direct connection for 24 V~ or 24 V=, continuous activation also permissible at 230 V
- Two-part housing made of self-extinguishing yellow plastic and sealing to IP66 protection class
- Maintenance-free gearbox in sintered steel, gearbox base-plate in steel
- Patented drive-valve coupling
- Mounting column made of stainless steel and mounting bracket for fitting valve made of cast light alloy
- Electrical connections (max. 2.5 mm²) with screw terminals
- Three knock-out cable entries for M20 x 1.5 (2x) and M16 x1.5
