Function, section, symbol
Pressure valves of type DBD are direct operated pressure
relief valves to be installed in block designs. They are used
for limiting a system pressure.
The system pressure can be set via the adjustment
type (5).
In the initial position the valve is closed. Via control line
(1) and poppet (2), the pressure in the main port
①
acts
on the spring plate (3). If the pressure in the main port
①
rises above the value set at the compression spring (4),
the poppet (2) opens and the hydraulic fluid flows into the
main port
②
.
