BALANCED 2-WAY AND 3-WAY HYDRONIC VALVES

Zone Valves
Application
Honeywell VC Series balanced 2-position hydronic valves are
used in domestic and small commercial heating and cooling
applications to control the flow of hot and/or cold water. They
consist of an actuator, valve and a cartridge assembly
2-way valves are designed for on-off zone control of domestic
systems. 3-way valves can be piped for either diverting or
mixing valve applications in domestic central heating and/or
cooling systems. Both versions can be used to control indi-
vidual fan coil, radiator, space heater or convector applica-
tions. Depending on the model selected they can be con-
trolled by a low or line voltage SPST or SPDT controller such
as a room thermostat, aquastat or flow switch.
VC Series hydronic valves are designed to take advantage of
sinusoidal valve actuator travel, and therefore operate silently
and reduce water hammer. Through internal logic the actua-
tor only takes power while driving the valve to the com-
manded position.
The actuator head is removable without affecting the integrity
of the water system. All actuator versions are interchangeable
with any valve body, offering the highest flexibility for boiler
production line assembly, and maintenance. The valve piston
construction allows for port sealing that is independent of the
differential pressure across the valve. Flow through the 2-way
valve can be in either direction, so the ports are not desig-
nated. 3-way valves are suitable for both diverting water from
AB to A or B, and from A or B to AB.
