These pressure control valves are avail-
able in the basic VMP* maximum pres-
sure, VSP* sequence and VUP* exclu-
sion versions, with a single pressure
value and three calibration ranges that
cover the band 15 ÷ 400 bar. It is possi-
ble to use auxiliary pilot valves, which
can be the simple standard AD3E
solenoid valve, by the mere exchange
of covers. These valves have been
fitted with an important safety feature
for the operation of the system where
they are used; a mechanical end of
stroke stop prevents the operator from
setting pressure values higher than
those specified in the catalogue (it is
impossible to compress the spring com-
pletely). In the standard configuration
these valves are supplied with a 1.6
bar main spring and with calibrated ø1
mm pilot feed orifice (Variant part No.
00).
Subplate mounting valves are suitable
for covers which do not conform to DIN
standards type C*P16/25.. whilst in line
mounting valves are suitable for DIN
standards covers type KEC16/25...
