New Original Siemens SAS61.03 Electric Valve Actuator
Product Overview
This is an original Siemens ACVATIX SAS61.03 non‑spring‑return electromotoric stroke valve actuator, delivering 400 N positioning force with 5.5 mm nominal strokehit.sbt.si…. It runs on AC/DC 24 V power supply and accepts 0‑10 V DC or 4‑20 mA modulating control signals, meanwhile providing 0‑10 V DC position feedback signal. It directly mounts on Siemens VVG44, VXG44, VVG55 series 2‑port and 3‑port modulating valves, widely used in HVAC heating, cooling, chilled‑water and hot‑water circulation systems for building automation, heat‑exchange stations and air‑handling unit water‑loop flow regulationdocs.rs-on…. No spring‑return function; the actuator stays in‑place upon power loss.
Main Functions
- Proportional modulating drive for linear‑stroke control valves, continuously adjust valve opening according to analog control signal.
- Output 0‑10 V DC real‑time valve‑position feedback signal for upper‑level controller closed‑loop monitoring.
- Built‑in manual override knob for manual valve position adjustment during commissioning, debugging or maintenance.
- Visual position indicator shows current valve opening status on‑site.
- Support optional auxiliary switch ASC10.51 for additional limit‑position signal output.
- Tool‑free direct mounting for matched valve bodies; compatible with legacy valves by using ASK30 adapter kithit.sbt.si
- Parallel multi‑actuator driving is available for multi‑valve synchronous control within system design limits.
Technical Features
- 400 N positioning force, 5.5 mm nominal stroke, full‑stroke running time 30 secondshit.sbt.si
- Non‑spring‑return (fail‑in‑place) design; keeps current position when power supply fails.
- Dual‑input support: DC 0‑10 V or DC 4‑20 mA control signal; 0‑10 V DC position feedback output.
- Operating power supply AC/DC 24 V, wide input voltage tolerance.
- IP54 protection rating, suitable for indoor HVAC equipment cabinet installationhit.sbt.si
- Manual adjuster with position lock function for on‑site setup.
- Compact housing structure, multiple mounting orientations from upright to horizontal.
- Compliant with CE, RoHS and EN 60730 safety standards for building automation equipment.
