Bosch Rexroth material number 0811402080 corresponds to type DREBE6X-1X/175MG24K31A1M. It is a pilot-operated proportional pressure reducing valve for controlled reduction of hydraulic pressure in a subplate-mounted size 6 assembly.

The type code identifies component series 1X, 24 V DC electronics, a seven-pole electrical connection, a 0-10 V command-value interface and NBR sealing. The integrated electronics arrangement reduces the need for a separate valve amplifier while preserving an analog command interface.

• Combines the pilot-operated hydraulic stage with onboard electronic control.
• Uses an analog 0-10 V command signal for proportional pressure setting.
• Employs a 24 V DC supply and K31 seven-pole electrical connection.
• Provides a size 6 subplate-mounted installation concept.
• Uses NBR seals as identified by the final M in the type code.
• Supports repeatable electrical adjustment of the reduced pressure rather than manual-only setting.

• Hydraulic circuits requiring electrically commanded pressure reduction in channel A.
• Machine functions where the reduced pressure must follow an analog controller command.
• Retrofit or repair of an installed DREBE6X-1X valve with the identical 175MG24K31A1M suffix.
• Subplate assemblies designed for the documented size 6 connection pattern.
• Closed machine-control systems using a 24 V DC supply and 0-10 V analog setpoint.

• Preserve the full type code because pressure rating, electronics interface, connector and seal material are all suffix-dependent.
• Record the installed hydraulic symbol, subplate pattern, port assignment and maximum circuit pressure before exchange.
• Confirm that the controller provides the required A1 0-10 V command interface and 24 V DC supply.
• Check hydraulic-fluid compatibility with NBR seals and maintain the filtration and commissioning practices for the host system.
• After replacement, verify electrical zero, commanded pressure response, leakage behavior and circuit pressure limits.

What is the complete type code for material 0811402080?

The complete identification is DREBE6X-1X/175MG24K31A1M.

What does G24 indicate in this valve code?

G24 identifies a 24 V DC supply for the valve electronics.

Which command signal does the A1 version use?

The A1 interface uses a 0–10 V command-value signal.

Are the control electronics integrated?

Yes. The E designation identifies an arrangement with onboard electronics.

Can another 081140208x material be used without review?

No. Adjacent material numbers can have different pressure ratings or interfaces, so the full material and type code must match.

Which installation details should be checked before fitting the valve?

Verify the size 6 subplate pattern, port function, 175 bar pressure code, K31 connector, 24 V DC supply, 0–10 V interface and NBR compatibility.
