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