VC Series
Zone Valves
BALANCED 2-WAY AND 3-WAY HYDRONIC VALVES
Design
VC Series zone valves consist of:
• 2-way or 3-way valve housing available with various
connection ends
• Spindle and cartridge assembly
• Actuator with cable or Molex™ socket
• Pipe fittings (most versions)
Materials
• Valve housing made of bronze
• Spindle made of stainless steel
• Cartridge made of Ryton™ (polyphenylene sulphide) and
Noryl™ (polyphenylene oxide)
• O-ring seals made of EPDM rubber
• Actuator cover made of Noryl™ (94V-0)
• Actuator base made of Ryton™ (94V-0)
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.
Features
• Rugged design
• Control by a low or line voltage SPST or SPDT
controller
• Minimal actuator power consumption
• Pressure differential up to 4 bar
• Double insulated actuator
• Quick connect electrical connections
• Quick and easy replacement of moving parts
• Actuator head installation does not require draining of
the system
• High flow rate capacity
