Proportional pressure relief valve
Flange and sandwich construction
• p
max
= 400 bar
DESCRIPTION
Pilot and direct operated proportional pres-
sure relief valves NG6. Flange and sandwich
construction according to ISO 4401-03 with 4
ports. Incorporated are proportional pressure
relief cartridges size M22x1,5 according to ISO
7789. The ange and sandwich bodies made
of steel are phosphatized.
APPLICATION
The valves have their applications in hydraulic
systems in which the pressure frequently has to
be changed. The facility for remote control and
signal processing from process control systems
enable economical solutions to problems with
repeatable sequences.
TYPE LIST / FUNCTION
Flange construction: Sandwich construction:
B..SA06 - P B..SA06 - BB..SA06 - A B..SA06 - ABB..FA06-P
FUNCTION
By adjusting the electric current to the pro-
portional solenoid the operating pressure in
hydraulic systems is limited by relieng the
uid from the protected lines P, A, B or A and
B to the return / tank line T. Back pressure in T
inuences the pressure in the reliefed pressure
lines. This proportional pressure relief valves
are adjustable very sensitivly. To control the
valve proportional ampliers are available from
Wanduh (see register 1.13).

sheets of the corresponding installed screw-in cartridge.
CAUTION!
The performace data especially the „pressure-ow-

catridges refere to the screw-in cartridges only. The
additional press-ure drop of the ange body respectivly
sandwich body must be taken into consideration.
