The kit, composed of a 3-way motorised valve, an actuator and related hydraulic fittings, is suitable for installation in fan coils with both
right and left connections.
The valve is an "all-or-nothing" type, typically closed.
Valves with 230V~50Hz power supply
for fan coils:
- with standard coil
VCF43),
- with heating only coil (BV)
(VCF45).
Valves with 24V~50Hz power supply
for
fan coils:
- with standard coil
(VCF4324),
