Description Size 10 Component series 2X Maximum operating pressure 350 bar Maximum flow 120 l/min Features Sandwich plate valve Porting pattern according to ISO 4401-05-04-0-05 4 pressure ratings, optional 3 adjustment types, optionally: • Spindle with hexagon • Rotary knob • Lockable rotary knob with scale 5 circuit options Corrosion-protected design Product description Pressure valves of type ZDB10D and Z2DB10D are direct operated pressure relief valves in sandwich plate design. The valves basically consist of housing (1) with seat (2) and control spool (3). The system pressure is set via the adjustment type (4). The valves are closed in their rest position and protect a hydraulic system and its components against excessive pressures. These valves respond quickly, noiselessly and in a virtually leakage-free manner. Thanks to the seat design, they are resistant against oil contamination. The integrated damping of the control spool (3) ensures extremely stable behavior and a low pressure increase with increasing flow. In the state as delivered, the valves are set to the minimum possible pressure. The system pressure applied to channel P acts on the control spool (3). If the system pressure increases above the set value, the control spool (3) opens and the hydraulic fluid flows from channel P in channel T. This limits the system pressure to the set value. For version “MP”, the set system pressure can be recorded and monitored using a pressure load cell at the measuring port (5) (see dimensions) Type ZDB 10 DP2..MP… Notice: Deviating from ISO 4401, port T is referred to as TA and port T1 is referred to as TB in this data sheet.
