MAIN CHARACTERISTICS

V3B and FV3 valves are designed for domestic heating and cooling systems. They offer important featuers such as: limited bluk, easy installation, very low leakage, equipercentage regulation curve, suitability for use with potable water and others. These valves are controlled manually by an external handwheel (see Fig. 1) and at any time can be controlled with MUT electric servomotors V3 series and/or by motors commonly found on the market. This can be done by totally unscrewing the manual control knob and screwing the electric servocontrol motor ring in its place. This can be done without having to drain the system.
