Product Overview

The MCV116F3118 is a Danfoss Pressure Control Pilot (PCP) used within the control system of Danfoss Series 90 variable displacement pumps. Danfoss identifies the part specifically as “PCP, Deutsch connector” in its official Series 90 parts documentation.

The MCV116F3118 is not a conventional stand-alone hydraulic directional valve or a main pressure-control valve. It functions as a pilot-stage pressure control component within the pump-control circuit.

Danfoss documentation shows the MCV116F3118 installed as item M9 in the KE control configuration of Series 90 variable displacement pumps. The same documentation lists MCV116G4211 as the PCP for the KK control configuration.

The related MCV110A1058 is also a Danfoss PCP, but uses a Packard connector, while MCV111BB0502 is a different control component corresponding to the 8002M0EA-B Electrical Displacement Control (EDC).

For aftermarket replacement, the correct selection must therefore be based on the complete Series 90 pump configuration, control code, MCV part number, connector and associated feedback/EDC components.

Our replacement process can be engineered for in-place interchangeability and verified through 100% simulated operating-condition testing before shipment.

Key Technical Advantages

1. Precision Pilot-Pressure Control

The MCV116F3118 and MCV116G4211 are Pressure Control Pilots, meaning they operate as precision control-stage components rather than main-flow hydraulic valves.

This allows a relatively small pilot-control function to influence the larger variable-displacement pump control system.

2. Direct Compatibility with Series 90 Control Architectures

Danfoss parts documentation associates each MCV component with specific Series 90 control configurations.

For example:

• MCV116F3118 → KE control
• MCV116G4211 → KK control
• MCV110A1058 → multiple earlier Series 90 configurations
• MCV111BB0502 → EDC control configuration

This makes the control-code relationship an important part of correct component identification.

3. Integration with Mechanical Feedback

For Series 90 EDC systems, Danfoss describes the EDC as a two-stage electrohydraulic pump stroke control using mechanical feedback to establish closed-loop control of the pump swashplate angle.

The PCP, EDC, feedback link and associated hydraulic control elements therefore operate as an integrated control chain.

4. Defined Connector Configurations

The component variants use defined electrical interfaces:

• MCV116F3118: Deutsch
• MCV116G4211: Deutsch
• MCV110A1058: Packard
• MCV111BB0502: EDC control component rather than PCP

Connector configuration should therefore be verified before electrical replacement.

5. Suitable for Series 90 Repair and Retrofit

Danfoss continues to document these components and their historical Series 90 control applications in current parts manuals. This makes the MCV components relevant for legacy pump repair, control restoration and replacement engineering.

Application Areas

Typical applications include Danfoss Series 90 variable displacement axial piston pump systems used in:

• Mobile hydraulic machinery
• Construction equipment
• Road-building machinery
• Material-handling equipment
• Industrial hydraulic power units
• Closed-circuit hydraulic systems
• Series 90 pump repair
• Pump-control assembly replacement
• Legacy hydraulic equipment refurbishment

The MCV116F3118 and MCV116G4211 must be selected according to the relevant KE or KK control configuration, rather than by MCV family number alone.

The MCV111BB0502 / 8002M0EA-B belongs to a different functional category: electrical displacement control for Series 90 pump swashplate regulation.

Expert Maintenance Tips

1. Identify the Complete Pump Control Configuration

Before ordering a replacement, verify:

Series 90 pump size + control code + serial/date range + MCV part number

Danfoss documentation specifically distinguishes MCV116F3118 for KE control and MCV116G4211 for KK control.

2. Preserve Original Orifices

Danfoss Series 90 parts documentation specifically instructs technicians to transfer the orifices installed in the original control to the replacement control when required.

If the replacement contains pre-installed orifices, they must be handled according to the manufacturer’s instructions rather than blindly duplicated.

This is a critical detail during Series 90 control replacement.

3. Inspect the Feedback Link

The PCP/EDC system operates together with a mechanical feedback link. Danfoss lists the feedback link in the same control assembly as the PCP.

A worn, incorrectly adjusted or damaged feedback mechanism can produce poor pump-control response even when the PCP itself is correctly installed.

4. Check the Deutsch Connector

For MCV116F3118 and MCV116G4211, inspect:

• Connector pins
• Wiring continuity
• Contact resistance
• Connector locking
• Seal condition
• Control-circuit supply

Both parts are officially identified by Danfoss as PCP, Deutsch connector.

5. Do Not Substitute MCV111BB0502 as a PCP

MCV111BB0502 corresponds to the 8002M0EA-B EDC, which performs electrical displacement control. It is not functionally equivalent to the MCV116F3118 or MCV116G4211 PCP.

The common “MCV” prefix does not mean these components are interchangeable.

6. Perform Functional Verification After Replacement

A successful replacement should not be judged only by the absence of leakage.

Recommended verification includes:

• Command signal
• Pilot-pressure response
• Swashplate response
• Standby condition
• Displacement response
• Pump output flow
• Load-transition stability

Our replacement components can be subjected to 100% simulated operating-condition testing before shipment to verify control response and functional stability under representative pump-control conditions.

Engineering Replacement Assurance

For MCV116F3118, MCV116G4211, MCV110A1058 and MCV111BB0502, the correct engineering approach is to identify the actual Danfoss Series 90 control architecture first, then match the corresponding control component.

The objective is not merely dimensional replacement, but functional interchangeability within the original pump-control system, supported by controlled assembly, component inspection and 100% simulated operating-condition testing.
