R983037993 DBDH10G1X/315 Rexroth plate overflow valve, original from Germany

FAQ:

Q1: What is the main function and application of the Rexroth DBDH10G1X/315 valve?

A:​ It is a high-performance, two-stage pilot-operated relief valve designed in a cartridge/sandwich plate style. Its primary function is to limit the maximum system pressure​ in a hydraulic circuit. It is typically installed in a custom manifold or valve block via a subplate, allowing for compact system design. It is widely used in mobile and industrial hydraulics where precise pressure control and space-saving integration are required.

Q2: What does the "315" in the model number signify?

A:​ The number "315" indicates the maximum adjustable pressure setting​ for this valve, which is 315 bar. This is the highest pressure that can be set on the valve's adjustment mechanism.

Q3: How is the DBDH10G1X/315 valve installed? How is it different from inline valves like the DB series?

A:​ Unlike inline valves (e.g., DB series) that are plumbed directly into the piping, the DBDH10G1X/315 is a cartridge-type valve. It is designed to be inserted into a machined cavity of a manifold or valve block and is secured via a cover plate. It uses a sandwich plate or subplate​ (typically conforming to ISO 4401 standards) to provide the interface between the valve and the manifold's internal flow channels. This allows for a very compact, leak-resistant, and integrated system layout.
