3WW motor driven mixing valve
3-way diverter valve with 230 V electric motor drive is used in closed solar and heating circuits for hydraulic switching or locking. Actuator with 2-point activation. Suitable for heating and solar circuits as well as drinking water. The valve can also be installed mirrored. The flow path can be modified by changing the position of the pins for the direction of rotation of the motor on the circuit board by 90°.
