APPLICATION
Pressure relief valves type DB... serve to limit pressure
in a hydraulic system or in its part, while in version
DBW... with pilot valve it is also used to unload
pressure in a system. Application example:
•DB... for setting up maximum pressure in a system
•DBW... for actuation of a pump without pressure
The valve is complied with the regulations of directive
2006/95/WE for the following voltages:
voltages
•50
50 – 250 V for AC
•75
75 – 250 V for DC

Pilot operated pressure relief valve type DB... consists of
the pilot valve (2) and the main valve (1). Pressure in a
system through line P affects the lower side of the
spool (4) and via jets (9), (10), (11) also affects its upper
side and the poppet (6) of the pilot valve. At standstill,
the pressure is equal on both sides of the spool.
A spring (7) holds the spool (4) in the starting position.
Lines P and T are separated from each other. If pressure
in a system reaches the value set by the position of the
Type DB
T
adjustment element (5) and tension of the spring (3) of
the pilot valve, the pilot poppet (6) opens and fluid flows
via jets (9) and (10) and opened pilot valve (2) to a tank.
The flow of control stream causes pressure drop at
jets (9) and (10). In effect pressure acting on the lower
side of the spool (4) is greater and the spool moves
upwards, what allows excess fluid to be drained to a
tank and pressure in a system to be limited to the set
value.

Pressure relief valve is also available in version with
forced (electrically) pressure unloading. Pilot valve (8) in
form of a directional valve shuts off drain line before
the pilot poppet in its starting position. The valve
functions as described before. After switching
directional valve (9) the chamber before the pilot

poppet is connected to drain line (connected to a tank).
The unloaded spool (4) moves upwards opening
connection between P and T. The valve is available in
two versions depending on the pilot valve (8): closed in
de-energized position – version DBW…A

in de-energized position – version DBW…B

ASSEMBLY AND APPLICATION REQUIREMENTS
1. Only valve working properly and suitably installed may
be connected to an electric system. Only skilled workers
are allowed to connect and disconnect electric system.
2. Ground connection ( ) must be connected with
protective earth wire ( PE)
PE in supply system according to
appropriate instructions.
3. It is forbidden to apply the valve if the supply cable in
the gland of plugplug-in connector is not properly tightened.
Type DB
-3-
4. It is forbidden to apply the valve if the plugplug-in
connector is not properly tightened to the solenoid
socket and is not secured by screwing bolt tightly.
5. Due to heating solenoid coil,
coil, the valves should be
placed in order to eliminate the possibility of incidental
touch while using, or, they should be equipped with the
coil covers (in accordance with the European standards
PN - EN ISO 1373213732-1 and PN - EN 982).
