Siemens Acvatix actuator SKC
Electromotoric actuator for the operation of Siemens 2-port and 3-port valves VXF with 40 mm stroke.
Function: regulating the desired flow temperature in transport line or mixing group.
The hot water from the boiler is mixed in the three-way mixing valve with water from the return pipe to achieve the desired flow temperature. By adjusting a rotating segment in the mixing valve, the ratio can be determined. The valve position is controlled automatically by a signal from the climate control system/computer; if the water temperature deviates from the desired temperature, a signal is sent to the actuator which sets the valve to the desired position.
