DESCRIPTION
The VJ 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 and a valve.
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, convector heat exchanger in combi
boiler applications.
Depending on the model selected they can be controlled by a
low or line voltage SPST
controller, such as a room
thermostat, aquastat or flow switch. The 2 wires Vdc version
can be controlled by a -10Vdc/20Vdc reverse-phase system.
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.
3-way valves are suitable for both diverting water from AB to A
or to B and from A or B to AB.

CONSTRUCTION AND OPERATION
All moving and sealing parts of the valve are constructed in
the cartridge assembly.
The piston is sealed with ”O”-rings.
pipe connections to suit the different applications.
When 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.
For the actual valve rating please refer to the specification
section.
The valve pressure loss characteristic is dependent on the
pipe connection/dimensions

Operation
The movement of the electric actuators is produced by a
screw spindle which is driven in both directions by a
synchronous motor through a set of gears. The motor is
switched OFF electronically when the actuator reaches the
end positions. The actuators are fixed to the valve body by
means of a coupling ring requiring no tools for mounting. The
actuators are maintenance-free and furnished complete with a
ready-to-wire connecting cable

INSTALLATION
To install a replacement actuator head
IMPORTANT
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.
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 MolexTM connector and remove. Where
appropriate, label wires for rewiring.
Remove the clip (1) and pull the actuator (2)
NOTE:
CAUTION
The actuator can be installed at 360°.
• Install the new actuator head by reversing the process.
• Reconnect MolexTM connector.
• Restore power.
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. 6.)
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.

ADJUSTMENT, CHECKOUT AND SERVICE
Service
Checkout
• Raise the setpoint of the thermostat above room temperature to initiate a call for heat. .
WARNING
The VJ 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:
9
The VJ 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.
