NG35 is a high-flow version of NG32, ports P, A, B and T
have ∅ 50 mm in the main stage. Contrary to standard
ISO 4401-10-09-0-05, ports P, A, B and T may be drilled to
max. ∅ 48 mm in the control block. These valves therefore

Function, sectional diagram
Functional description
When the control solenoid is not actuated, the control
spool is held by springs in the fail-safe position, and
the main stage spool remains in its spring-centered mid
position.
In the on-board electronics, the pre-defined setpoint is
compared with the actual value for the position of the main
stage control spool. In the event of an error signal, the
control solenoid is actuated, and the pilot spool is moved
as the magnetic force changes. The flow released through
the control cross-sections causes the main control spool
to move. The spool stroke is controlled proportionately to
the setpoint of 0.5...10 V between 20...100 %. If the input
setpoint is < ± 0.5 V, the control spool is held in the spring-
centered, overlapped mid position.
The control oil is conveyed to the pilot valve either internally
via port P or externally via port X. The oil returns to the tank
internally via port T or externally via port Y.
Power failure
In the event of a power failure or an open circuit, the
on-board electronics cut off the electricity to the control
solenoid and the pilot spool moves to the fail-safe position,
relieving the control oil chambers of the main stage. The
main stage control spool is held by springs in mid position.

– Pilot valve (1) with control spool and sleeve, return
springs, control solenoid and inductive position
transducer
– Main stage (2) with centering springs
and position feedback
– On-board trigger electronics (3)

Technical data
Important
Pilot operated 4/3-way servo solenoid directional control valves
with positive overlap perform their function in open or closed-
loop-controlled axes and have approx. 20 % overlap when
switched off.
This condition does not constitute an active fail-safe position.
For this reason, many applications require the use of “external
check valves” or certain sandwich-mounted valves, which must
be taken into account during the On/Off switching sequence.

Control spool with asymmetric metering notches
Control spools with asymmetric metering notches are
available in a ratio of 2:1 for the purpose of adaptation to
differential cylinders.
Control spools in a differential circuit
In order to produce differential circuits, valve spools with
a 4th position are available.
It is sufficient to install a check valve in the consumer lines.
In addition, a control spool (symbol) with internal B-P con-
nection is employed for certain branch-oriented solutions.
However, we recommend that you consult the BRH
Application Center with regard to these special symbols, as
a simulation or knowledge of this type of system is usually
required.
Flow in mid position, “leakage oil pressure relief”
With symbol “E”, leakage oil in the two work chambers
A and B of the control piston gives rise to a build-up of pres-
sure in A or B, which then causes a connecting cylinder
to drift out of position.
In many cases, the “W” symbol is a better solution. With
a setpoint of “0”, the control piston moves into the over-
lapped mid position. In this mid position, pressure is then
relieved from ports A and B with 1 % ± 0.5 % Q
N
to T.
This also supports the function of external check valves.

Load tap C1/C2
To compensate for fluctuations in the load or supply
pressure, 4/3-way servo solenoid directional control valves
are combined with pressure compensators. The load is
tapped via a shuttle valve for the NG10 and 35, and via two
additional ports C1 and C2 for the NG16, 25 and 27.
The pressure compensator therefore always receives the
correct pressure signal even in the event of negative load.
When using pressure compensators, an external control oil
supply should always be selected.
