P27T3 actuator is a device used to operate the rotary mixing valves. It can be applied to all Barberi® mixing valves, 3 or 4-ways, apart from flanged mixing valves. The actuator is equipped with an integrated control which, through a Pt1000 probe, adjusts the water temperature in a fixed point mode within the 5–90 °C range. The article is equpped with supply cable and European standard plug with 2 directly connected poles, integrated Pt1000 temperature probe, mixing valve adaptor and anti-rotation pin. The actuator is normally used to control the flow temperature in fixed point mode, to control the return temperature to solid fuel generators with anti-condensation function, for fixed regulations on heat exchangers.
