Merten 639125 thermoelectric actuator 230 V polar white content_copy

Thermoelectric valve actuator 230 V. Thermoelectric valve actuator for opening and closing valves. For 2-point or PWM control of heating, air conditioning and ventilation systems, individual room control of surface heating, control of heating circuit distributors. For radiators, heating convectors, cooling ceilings. Operation is via the heating actuator REG-K/6x24/230/0.16A, fan coil actuator REG-K or a room temperature controller (230 V) with 2-point or PWM output. Valve adapters enable compatibility with a wide range of valve bodies and heating circuit distributors. Functions: First-open function: The actuator is set to open when de-energized at the factory. This allows the heating to be operated during the shell construction phase. Closed when de-energized. Function display (open, closed, intermediate positions). Adjustment control. Pluggable connection cable. Pluggable installation. Supply voltage: AC 230 V, 50/60 Hz. Starting current: max. 350 mA for max. 100 ms. Power consumption: 1 W. Stroke: approx. 4 mm. Running time: 3.5 min for 4 mm. Positioning force: 100 N ± 5 %. Temperature of the circulating medium: 0-100°C. Protection class: IP 54 / II, in all installation positions. Connection cable: 1 m, 2x0.75 mm², plug-in. Dimensions: 59.2x44.3x56 mm (HxWxD). Color: polar white.
