EBV-CMAP Manual And Motorized Butterfly Valves

The EBV butterfly valve series are suitable for the adjustment of cold or hot air flow in low pressure ducts.




The EBV-CMAP valves with ECON-O motor units
have a rnage of 0 ~ 90°. All the motor units have a manual command station, two auxiliary switches set at 10° and 80° and a signal for the feedback of the point reached. In particular, for the models with the open/close command, feedback takes place via an ohm resistor. While in the models with the proportional command a similar signal is available in volts.
