The Z2DBY6DC2-1X/315V/60 relief valve is produced by Bosch Rexroth for the ZDB Pressure Relief Valves series and is intended to limit pressure in hydraulic automation circuits. The unit uses a sandwich plate connection that matches the ISO 4401-03-02-0-05 porting pattern and fits size 6 sub-plates. A maximum operating pressure of 315 bar allows the valve to protect high-pressure lines, and the maximum set pressure is also 315 bar so the user can adjust to full system rating. Flow capacity reaches 60 l/min to accommodate medium-volume circuits, and the design tolerates up to 40 bar counter pressure on the tank line. Cleanliness must meet ISO 4406 20/18/15 to prevent wear, while FKM seals provide chemical resistance for standard hydraulic oils.
Installation parameters are defined for secure mounting and accurate adjustment. The adjusting screw accepts a hexagon wrench size 10, and the lock nut is tightened to 50 Nm to hold the selected relief setting. A Ø4 × 4 mm locating hole on the component side and a Ø3 × 5 mm locating hole on the plate side position the valve precisely within a stacked manifold. Service temperatures for FKM seals range from −15 °C to +80 °C, ensuring reliable pressure control in typical industrial environments.
