FAR V3PZV1 Motorized Zone Valves
MOTORIZED ZONE VALVES WITH QUICK-COUPLING INSTALLATION
ACTUATOR
- Place the actuator on the stem of the zone valve
- Lower the locking ring
- Turn the ring clockwise up to the end of the stroke
ELECTRICAL CONNECTIONS
Example of an actuator connection to a terminal. The blue wire must be
connected directly to neutral, the brown and the black to the thermostat. The
red and the green wires must be connected to the common contact and to a N.O.
auxiliary microswitch.
NB: To reverse the rotation of the actuator, and then switch the signal
from ‘normally open’ to ‘normally closed’, reverse the connection of the
black wire with the brown.
ART.307075 – 307175 – 307077 – 307177 2-WAY ZONE VALVE
The zone valve features a special anti-blockage system inside, which prevents the valve from blocking in even the worst operating conditions. All models of zone valves feature this system.
ART.307080 – 307180 – 307082 – 307182 3-WAY DIVERTER ZONE VALVE
3-Way zone valve with “L” passage is a diverter valve with fluid inlet from
below and fluid delivery to the thermal carrier towards right or left as a
function of the position of the actuator (Pic.1); or entering from right or
left and diverted towards the centre (Pic.2).
This valve is ideal for the commutation of the system, depending on the change
of seasons.
Before installing the actuator, it is essential to check that the flow aperture in the ball of the valve is positioned in the desired direction. The valve can be adjusted by means of a screwdriver. The silk-screen printing on the control stem shows the position of the ball.

DECLARATION OF CONFORMITY
FAR Rubinetterie SpA under its own responsibility declares that actuators are produced in conformity to the EEC standards: 2004/108CE and 2006/95CE.
2002/96/CE DIRECTIVE FOR THE RECOVERY OF WASTE FROM ELECTRICAL AND ELECTRONIC EQUIPMENT The 2002/96/CE directive on the ‘RAEE’ (waste from electrical and electronic equipment) states that they cannot be treated like the municipal solid waste, but must be managed separately. In order to carry out a correct recovery of the ‘RAEE’, apply to the local authority, which will have information about methods and procedures to follow, as well as about place and time for the waste delivery.
