ON/OFF 3-WAY VALVE KIT
On/Off 3-way solenoid valves with bypass (4 fittings) are available.
The valve body is in brass; an on/off electrothermal actuator (power supply 230Vac) controls the membrane. When there is no power supply the
valve is closed.
The electrothermal actuator is silent during operation.
The kit comprises valve body, electrothermal actuator, flared copper pipes, ring nuts and gaskets for fixing to the fan coil.
The valve kit is already installed on the fan coil complete with the water and electrical connections necessary for operation.
The fan coil model and the coil (standard or auxiliary) to which the kit refers must be specified at the time of ordering.
