General

Type DBETX proportional pressure relief valves are remotecontrolled (pilot) valves in conical seat design.

They are used to limit system pressure.

The valves are actuated by means of a proportional solenoid.The interior of the solenoid is connected to port T

and is filled with pressure fluid.

With these valves, the system pressure that needs to be limited can be infinitely adjusted by the valve amplifier

electronics in relation to the solenoid current, at an oil flow that is as close as possible to constant.

Basic principle

To adjust the system pressure, a setpoint is set in the trigger electronics. Based on this setpoint, the electronics

control the solenoid coil with regulated PWM (pulse-width-modulated)

current. The proportional solenoid converts the current to a mechanical force, which acts on a main spring by means

of the armature plunger. An “additional” spring between the cone and

the seat contributes to stability and a minimal residual pressure. The spring force acting on the cone and the pressure

in the valve seat balance one another at a constant oil flow

(0.7...1 l/min). The “pmax” pressure stage is determined by the cone and seating bore configuration.
