ON/OFF Linear Valve Actuator | Vaurien I & II Series | M30×1.5 Threaded Nut | 24 V AC/DC | IP54 Enclosure
ON/OFF Linear Valve Actuator | Vaurien I & II Series | M30×1.5 Threaded Nut | 24 V AC/DC | IP54 Enclosure
Vaurien I & II Series Thermoelectric Actuators deliver compact, reliable ON/OFF valve control for hydronic heating and cooling systems. Designed for direct use with RWV 9520 and 9707 Series valves, these actuators use low-power thermoelectric technology to provide quiet, maintenance-free performance with accurate open/close positioning.
Both models feature a M30×1.5 threaded connection and a quick-connect nut for easy installation, IP54 protection against dust and water splashes, and a 40 in pre-wired lead for flexible routing. Each actuator operates on 24 V AC/DC power and comes factory-set as Normally Closed (NC) — a Normally Open (NO) version is available upon request.
Key Features & Benefits
- Thermoelectric ON/OFF Actuation — Precise, low-energy valve control using thermal expansion; ideal for PICV, radiant, and fan coil applications.
- M30×1.5 Fast-Threaded Nut — Quick-connect design simplifies installation on RWV 9520 (Vaurien I) and 9707 (Vaurien II) valve bodies.
- Low-Power 24 V AC/DC Operation — Consumes only 1.0–1.2 W during actuation; meets BAA and CE requirements.
- IP54-Rated Housing — Dust- and splash-resistant enclosure with integrated 40″ cable for safe installation in tight spaces.
- Two Model Sizes — Vaurien I fits ½″–¾″ valves; Vaurien II fits 1″–1¼″ valves and offers greater thrust and stroke.
