Valve Actuator for Underfloor Heating Systems 230V (4 wires)

Description Valve Actuator for Underfloor Heating Systems The Valve Actuator is designed to control the flow of heating water to specific circuits in an underfloor heating manifold, opening or closing the circuit depending on whether heat is required. It provides efficient control and enhances the overall performance of your underfloor heating system. The thermal actuator is a high-quality 4-wire motorised valve actuator designed for underfloor heating manifolds, heating zones, and other ON/OFF control applications.It is available in 24V and 230V versions. Wiring – 4 Wires (Colour-Coded) Based on the wiring diagrams in the datasheet: BN (brown) – power BU (blue) – neutral BK (black) – auxiliary switch wire BK (black) – auxiliary return wire This is a TRUE 4-wire actuator with an auxiliary microswitch.The wiring diagrams on page 1 clearly show the 4 wires and their functions. Key Features ON/OFF actuator with 4-wire connection Auxiliary microswitch included (for boiler pump or zone control) Available in 230V AC/DC M30 × 1.5 threaded connection – fits most UFH valves 100 N closing force IP54 protection class Low power consumption: 2W Suitable for UFH manifolds, heating zones, fan coil units, etc. Technical Specifications Datasheet-4-wire-actuator Power supply: 230V Power consumption: 2W Frequency: 50–60 Hz Initial opening time: 24V: 6 minutes 230V: 6 minutes Final opening time: 24V: 75 seconds Actuator stroke: 3 mm Max valve stroke: 4 mm Operating temperature: 0–50°C Fluid temperature: up to 110°C Cable length: 1 meter Cable type: 4-core, 0.5 mm² Installation Notes Do not use tools (only tighten ring nut manually) Cable must not be replaced Faulty actuators must be replaced as a complete unit Do not install the actuator below the valve body Who This Product Is For Ideal for: Underfloor heating manifolds Heating zone control Systems requiring an auxiliary switch (e.g., to start boiler or pump) Installers needing 4-wire configuration with standard M30×1.5 fitting
