E5. PRESSURE CONTROL ELECTRO-VALVE
(for the version where foreseen)
It is connected to the delivery filter (P6) and to the tank (P1), through the pipe (T3). It adjusts the operating
pressure checking the backflow into the tank.

P7. P7. FILTER
It is connected to pressure regulator (P5) and, through pipe (T4), to the distributor (E9/P9). The filter
has a filtering capacity of 250 l/min., with a 50 mesh cartridge. The dirty cartridge causes the operating
pressure chute. This inconvenient is signalled by the pressure gauge. Mounted on the feeding pipe,
it only filters the delivery flow to the heads, by sensibly reducing the possibility for the cartridge to get
obstructed. On the body of the filter there is an attack, with internal thread 1/4", to make a functional
test of the gauge (P8).
open: in the tank both the backflow and
the agitaton of the mixture increase
while the values of the working pres-
sure and the delivery to the sprayhead
decrease.
