Honeywell VCZB Series Quick Start Manual

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.
