The valve assembly (10) has two load connections (A,B) for connecting a hydraulic load (11) and a pump connection (P) for connecting a pump (13). A pressure maintenance valve (22) is connected to the pump connection, so that it results a pressure (41) between the metering orifice and the pressure maintenance valve. The metering orifice is connected to a damping throttle (21) in series, so that another pressure (42) results between a metering orifice (20) and the damping throttle. The latter pressure is connected to a pressure limit valve (32), whose release pressure is adjustable. |
