ZDB10VA2-4X/200V

The ZDB10VA2-4X/200V valve belongs to the ZDB Pressure Relief Valves series produced by Bosch Rexroth. It is a pilot-operated pressure relief design intended to protect hydraulic circuits from overpressure during automation tasks. As a sandwich plate valve it stacks between manifold sections and reduces piping complexity. The unit provides an A-T relief path so flow from port A is diverted to the tank when the set limit is reached. The pressure setting can be adjusted through a sleeve with a hexagon head that is covered by a protective cap to discourage tampering. Its maximum working pressure is 200 bar, enabling use in medium-pressure systems common in industrial machinery.

For installation the valve contains one cartridge body, keeping the overall assembly compact and simplifying service in modular manifolds. The pilot drain is routed externally to the T port so pilot oil returns directly to the tank and avoids interaction with system pressure. An FKM seal package resists mineral oils and elevated temperatures, maintaining reliable sealing throughout continuous duty cycles. These attributes make the component suitable for automated equipment that demands consistent overpressure protection without frequent adjustments.
