Description Size 10 Component series 4X Maximum operating pressure 315 bar Maximum flow 100 l/min Features Sandwich plate valve Porting pattern according to ISO 4401-05-04-0-05 4 pressure ratings 6 circuit options With 1 or 2 pressure valve cartridges 4 adjustment types for pressure adjustment, optionally • Rotary knob • Sleeve with hexagon and protective cap • Lockable rotary knob with scale • Rotary knob with scale Corrosion-protected design Product description Pressure valves of type ZDB and Z2DB are pilot-operated pressure relief valves in sandwich plate design. They are used for limiting a system pressure. The valves basically consist of the housing (7) and one or two pressure valve cartridges. The system pressure can be set via the adjustment type (4). In the initial position the valves are closed. The pressure in channel A acts on the spool (1). At the same time, pressure is applied to the spring-loaded side of the spool (1) via nozzle (2) and to the pilot poppet (6) via nozzle (3). If the pressure in channel A exceeds the value set at the spring (5), the pilot poppet (6) opens. Hydraulic fluid flows from the spring-loaded side of the spool (1), nozzle (3) and channel (8) into channel T (TA). The resulting pressure drop moves the spool (1) and opens the connection from A to T (TA). In channel A, the pressure set at the spring (5) settles.
