Combined
pressure control valves
(1 zero pressure + 3 controlled pressures
or 3 controlled pressures)
Line and board assembly. Models: 75 and 125.
Sizes: 3/4” NPT and 1” 1/4 BSPT.
In
the case of complex hydraulic systems, where
an important number of pressures with different
values is necessary, this kind of valves simplifies
the circuit, since combining the pressure
regulation with the three positions –
two solenoids directional valve (2-SH-4-12-6-#
model) enables to obtain three different control
and independent pressures. When this combination
is joined by a two positions – one solenoid
directional valve (SH-4-12- 0a-# model) four
pressures can be obtained: one which discharges
to the tank and three other controlled pressures.
-
For the RPC-#-#-#-3PC-# model:
Without activating any solenoid regulation
or central body (0).
Activating solenoid (a) regulation of body
(2) (opposite to the solenoid).
Activating solenoid (b) regulation of body
(1) (opposite to the solenoid).
- For the RPC-3-#-#-4P-# model:
Without activating any solenoid – tank
discharge.
Activating the (a) solenoid of the simple
directional valve, central body (0) regulation
(this regulation shall always be the highest
of all regulated pressures.
Activating the (a) solenoid of the simple
valve plus the (a) solenoid of the double
valve that regulates the body (2) opposite
to the solenoids.
Activating the (a) solenoid of the simple
valve plus the (b) solenoid of the double
valve that regulates the body (1) opposite
to the solenoid (b).
