DESCRIPTION
The VC series 2--position hydronic valves are used in
domestic and small commercial 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 individual fan
coil, baseboard radiator or convector applications.
Depending on the model selected they can be controlled by a
low or line voltage SPST
such as a room thermostat, aquastat or flow switch.
or SPDTcontroller,
The VC series hydronic valves are designed to take avantage
of sinusoidal valve actuator travel and therefore operate
silently and without water hammer. Through internal logic the
actuator only takes power while driving the valve to the
commanded 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 designated.
3--way valves are suitable for both diverting water from AB to
A or to B and from A or B to AB.

EN2R--9011 0108R2--NE
CONSTRUCTION AND OPERATION
All moving and sealing parts of the valve are constructed in
the cartridge assembly.
The ports are sealed with ”O”-- rings on the outer surface of
the piston.
When the valve stem is driven down to open port A the water
will flow through the hollow piston to the other port.
In case of a 3--way valve with the piston driven down port B is
sealed, allowing flow between port AB and port A. With the
stem up the flow is between port AB and port B.
The VC series hydronic valves offer a variety of versions of
pipe connections to suit the different applications.
The valve pressure loss characteristic is dependent on the
pipe connection/dimensions
For the actual valve rating please refer to the specification
section.

INSTALLATION
IMPORTANT
Take care that installer is a trained experienced
service person.
When installing this product read these instructions
carefully.
Failure to follow them could damage the product or
cause a hazardous condition.
Check the ratings given in the instructions and on the
product to make sure it is suitable for your
application.
Always conduct a thorough checkout after
installation.
CAUTION
Switch off power supply before making electrical connections to prevent electrical shock and equipment
damage.
It is advisable to remove the actuator head from the
valve body for ease of installation.
Fit the actuator head in the most convenient position
for wiring.
On sweat fitted valves, the cartridge is shipped loose
or is removed to avoid being damaged during the
solder operation.
On 24 Volt systems, never short circuit the valve coil
terminals as this may burn out the heat anticipator in
the thermostat.
To remove the actuator head 25 mm clearance is
needed above the actuator.
Plumbing (see fig. 10.)
The valve may be plumbed in any angle but preferably not
with the actuator head below the horizontal level of the valve
body. Make sure there is enough room around the actuator
head for servicing or replacement.
When used to form a part of a central heating system, do not
locate it where it will block the system vent, cold feed or any
bypass when the valve is closed
Mount the valve directly in the tube or pipe. Do not grip
actuator head while making and thightening plumbing
connections. Either hold valve body in your hand or attach
adjustable spanner across the hexagonal or flat faces on the
valve body.
Compression models
For compression fitted models, tighten the compression nuts
enough to make a watertight seal.
Take care not to overtighten.
Maximum torque limit is 33 ft--lb for the 22 mm compression
fitting and 48 ft--lb for the 28 mm compression fitting.
Fig. 10. Plumbing
Sweat models
On sweat fitted valves, the cartridge is shipped loose to avoid
being damaged during the solder operation.
Remove valve actuator from body and solder the
connecting pipes in accordance with normal soldering
practices.
After soldering and valve has cooled, remove cartridge
assembly from plastic bag, insert into the valve body and
tighten down with enclosed wrench until it bottoms out. Do
not overtighten (maximum torque is 40 ft--lb).
The top surface of the cartridge will be flush with the top
edge of the body casting.
Replace valve actuator.

EN2R--9011 0108R2-- NE
To install a replacement actuator head
IMPORTANT
Installation of a new actuator head does not require
draining the system providing the valve body and
cartridge assembly remain in the pipe line.
Disconnect power supply before servicing to avoid
electrical shock or equipment damage.
Disconnect leadwires to actuator head, or depress
tabonMolex
TM
connector and remove.
Where appropriate, label wires for rewiring.
The actuator head is automatically latched to the valve
(see fig. 11.) To remove lift up on the latch mechanism
located directly below the red manual open lever.
Press the actuator head down towards the valve body with
moderate hand force and turn counter--clockwise by
turn (45 degrees) simultaneously.
1
/
8
Lift the actuator head off the valve body.
NOTE: The actuator can also be installed at right angles
to the valve body but in this position the latch
mechanism is not engaged.
Install the new actuator head by reversing the process.
Reconnect leadwires or Molex
TM
connector.
Restore power.

ADJUSTMENT, CHECKOUT AND SERVICE
Manual opener
The manual opener can be manipulated when in the up
position.
The motorized valve can be opened by firmly pushing the red
manual lever down to midway and in (only possible if the
actuator is in the upper position).
This holds all ports in the open position and with auxiliary
switch models the NO switch is closed.
Ports A and B of 3--way valves are opened.
This ”manual open” position may be used for filling, venting or
draining the system or for opening the valve in case of power
failure. The valve can be restored manually to the closed
position by depressing the red manual lever ligthly and then
pulling it out.
The valve actuator returns to the automatic position when
power is restored.
Checkout
Raise the setpoint of the thermostat above room
temperature to initiate a call for heat.
Valve position indicator should move downward to the
open position.
For all auxiliary switch models, monitor the control devices.
2--way valve:
check that the valve opens, the auxiliary switch (if
present) closes and at the end of the opening
stroke the circuit to the circulator or another valve
is made.
3--way valve:
check that port A opens, port B closes, the
auxiliary switch (if present) operates and at the
end of the opening stroke the circuit to the
circulaotr or another valve is made.
Lower the set point of the thermostat below room
temperature.
Observe the control devices.
2--way valve:
check that the valve closes and all auxiliary
equipment stops.
3--way valve:
check that port A closes and all auxiliary
equipment stops.
Service
WARNING
The VC series hydronic valves should be serviced by
trained, experienced service personnel.
If the valve is leaking, drain system or isolate valve from
the system.
Check to see if the cartridge needs to be replaced.
If the gear train of the motor is damaged, replace the
actuator assembly.
NOTE: The VC series hydronic valves are designed and
tested for silent operation in properly designed and
installed systems.
However, water noises may occur as a result of
excessive water velocity.
Piping noises may occur in high temperature
(over 100 _C) systems with insufficient water
pressure.
