VC6800, VC6900 Series
Floating Control Valves
GENERAL
The VC6800/VC6900 Series Modulating Control Valves
provide optimum control of hot and/or chilled water flow
in various heating and cooling applications, such as fan
coil units, reheat coils and perimeter heating systems.
The VC hydronic valve consists of a valve body and
replaceable characterized cartridge assembly. When used
with a VC6800/VC6900 series actuator, the valve provides
linear flow in either diverting or mixing applications. They
are designed to provide sinusoidal valve actuator travel,
and therefore operate silently and resist water hammer.
Compatible with 24 Vac, 3-wire signal, the VC series valve
actuator is used with either a single pole double throw
two-position controller for on-off control, or a floating
controller for modulating control. These actuators have
conformal coated printed circuit boards for humidity
resistance. Through an internal switching mechanism, the
actuator takes power only while driving the valve to the
commanded position.
FEATURES
• All actuators are interchangeable and suitable for all
valves, 1/2" through 1", providing maximum
installation flexibility with minimum stocking
requirements.
• A locking tab secures the actuator to the body of the
valve.
• Multi-directional actuator mount allows for 4
different wiring orientations, thus providing ease of
wiring and service.
• Actuator is constructed of moisture and humidity
resistant materials.
• Long service life because the actuator motor
de-energizes when not in motion.
• Manual opener and position indicator. This "manual
opener" position may be used for filling, venting, and
draining the system.
• Bayonet-mount for actuator head. Actuator can be
installed after plumbing work has been completed,
which makes for more efficient on-site installation.
• Body dimensions are comparable to existing
products (V4043/4044 and V8043/8044), and in
most cases can be interchanged.
• Sweat-fitted valves are supplied with the cartridge
loose, to facilitate soldering operations (an
installation tool is included).
• In this balanced valve design, the internal piston
moves up and down, across the water flow. The
actuator provides sinusoidal piston travel action for
"soft" shut-off and open, to eliminate water hammer
in most applications.
• In 2-way valves, flow is bi-directional.
• In 3-way valves, flow can be mixing or diverting.
