Snap Zone Valve
DESCRIPTION
The B&G Snap Zone Valve is an on/off zone valve
for residential and light commercial HVAC
applications. The valve opens and closes based
upon the voltages applied to the actuator. Use the
B&G Snap Zone Valves to speed installation time
and reduce callback times to customers. The
actuator can be installed or removed at any angle on
the adapter ring. The compact design and versatility
in the actuator mounting position allows for easy
installation in difficult positions.
