direct controlpressure relief valveProduct Description:

DBD type relief valve is a direct acting seat valve. These valves are used to limit system pressure. These valves are mainly composed of the following components: sleeve (1), spring (2), valve core with damping plunger (3) (pressure rating 25 bar... 400 bar) or ball (4) (pressure rating 630 bar), and adjustment type (5). The adjustment type (5) can be used to continuously adjust the system pressure. The spring (2) pushes the valve core (3) or ball (4) onto the valve seat. Channel P is connected to the system. The pressure present in the system will act on the surface of the valve core (or ball). If the pressure in channel P exceeds the value set on spring (2), the valve core (3) or ball (4) opens away from spring (2). At this point, hydraulic oil flows from channel P into channel T. The stroke of valve core (3) is limited by embossing (6).

In order to achieve good pressure regulation throughout the entire pressure range, the entire pressure range has been divided into 7 pressure levels. A pressure level corresponds to the maximum working pressure that can be set for a specific spring.

Model DBDS. K1X/

Model pressure rating 25... 400 bar (lift seat valve)

Model DBDH 10 K1X/

Model pressure rating 630 bar (ball seat valve, NG10 only)

Note:

▪ The adjustment type (5) has been specially constructed to prevent its loss. Thanks to the design of the universal joint, the adjustment element in adjustment type (5) will remain loose (movable) after unloading.

▪ Pressure level "25": Although the adjustment type is in the unloading state, if the small pressure is not determined, the adjustment element will still "return" to the stop state under the action of a small spring force and/or restoring force.

▪ After pressure adjustment/lifting, the adjusting element can be screwed in again.
