Honeywell Home resideo VCZA Series Installation Instructions

VCZA,B,M,N Series
CARTRIDGE VALVE FOR USE WITH VC SERIES
The VC hydronic valve consists of a valve body and
replaceable characterized cartridge assembly.
Depending on the valve model selected, they can be used
with a VC2114 or VC8114 series actuator to provide on-off
flow control, or with a VC6930 or VC7930 series actuator
to provide proportional flow control. Two way bodies may
be plumbed in either direction. Three-way bodies may be
used in either diverting or mixing applications.
Replacing the cartridge rebuilds the valve. The valve body
should be able to stay in the pipes indefinitely.
VC actuators, ordered separately, use cam-operated
cartridge travel to resist water hammer. Limit switches
prevent motor overrun.
