P A B T P A B T Function, section Pressure relief valves types ZDB und ZDB are pilot operated and are of sandwich plate design. They are used to limit the pressure within a hydraulic system. They basically consist of the housing (7), together with one or two pressure relief valve cartridges. The system pressure is set by means of adjustment element (). At rest, the valve is closed. Pressure in port A acts on the spool (). At the same time pressure passes through orifice () on to the spring loaded side of spool () and via orifice () to the pilot poppet (6). If the pressure in port A rises above the value set on spring (5), the pilot poppet (6) opens. Fluid can now flow from the spring loaded side of the spool (), then via orifice (), and channel (8) into port T. The resulting pressure drop then moves the spool () thereby opening the connection A to T, while maintaining the pressure set at spring (5). Pilot oil return from the two spring chambers is taken externally via port T. Type ZDB 6 VA-... 5 6 8 7 A T P B A T P B ZDB 6; ZDB 6 /8 RK 5 75/0.0
