Drivers replica

L
The new driver replica feature is available on demand for the V230 twin pilot.
I
Driver replica are 4 quick connections installed on the lower part of the valve body, each
S
connection is linked to a side of the pressure chambers, hence it provides a pressure
H signal according to the position of the piston (see below picture). That pressure signal can
be used to drive external diaphragm valve, common applications are outlet shut off and
brine line shut off.
In order to use this feature, just remove the blue caps linked to the chamber from where it
is desired to take pressure, and connect a 6mm pipe to the plug.

Automatic BY-PASS

The automatic proportional by-pass accessory enhances the system with following
functions when fitted upstream of the water treatment system:
a) Supply of untreated water during regeneration cycle 4C, in this cycle the valve does
not provide hard water bypass during the regeneration.
b) If there is a temporary increase of the water consumption the pressure drop inside
the valve and through the resin bed increases substantially. In this situation, due to
the differential pressure that has been created from inlet and outlet sides of the by-
pass the automatic by pass valve opens to balance the outlet pressure with the inlet
pressure ensuring a higher flow rate at the outlet but of course obtaining in that case
an intermediate hardness during part of the service cycle.
c) Disconnection of the valve or the entire water treatment system without causing a
break in the supply of water. In that case only raw water is available for the user.
