KVME11201 Danfoss Electrical Displacement Control

Product Overview

The KVME11201, KVME11204, KVEBB1402, KVEBB1802 and MCV116G4201 belong to the Danfoss (formerly Sauer-Danfoss) Electrical Displacement Control (EDC) and pressure control pilot valve series. The KVEB/KVME series is a two-stage electrohydraulic pump stroke control that uses mechanical feedback for closed-loop control of the swashplate angle on Series 90 variable pumps. Fully interchangeable with original Danfoss units, every valve undergoes 100% simulated operating-condition testing for precise pump control in mobile hydraulic systems.

Technical Specifications 

• Model: KVME11201 / KVEBB1402 / MCV116G4201 etc.
• Type: Electrical displacement control (EDC) / pressure control pilot valve
• Full stroke current: approx. 14–18 mA (single coil) or higher (dual coil), configuration-dependent
• Scale factor: approx. 1.15–6.2 psi/mA (configuration-dependent)
• Input impedance: 20–650 Ω (configuration-dependent)
• Operating principle: Two-stage electrohydraulic with mechanical feedback closed loop
• Compatible pumps: Danfoss Series 90 variable displacement pumps
• Control method: Current signal controls swashplate angle
• Hydraulic fluid: Petroleum-based

Key Technical Advantages

1. Closed-loop mechanical feedback: Precisely controls pump swashplate angle for stable flow output.
2. Low-current high response: Achieves full stroke with low current for energy-efficient operation.
3. High interchangeability: Identical interfaces and performance to original Danfoss KVEB/MCV116 series enable direct drop-in replacement.
4. 100% functional verification under simulated conditions: Every unit is fully tested across current-to-stroke characteristics before shipment.

Application Areas

• Precise control of variable pumps on construction machinery
• Hydraulic systems on agricultural and material-handling equipment
• Closed-circuit pump control on mobile machinery
• Systems requiring electrical signal control of pump displacement
• Retrofit of Series 90 pumps with electrohydraulic control

Expert Maintenance Tips

Ensure clean ports and tighten to the specified torque. Maintain required fluid cleanliness. Match current range and polarity correctly during electrical connection. Periodically check null and stroke response. If control becomes unstable, first inspect fluid contamination and filters. For long-term storage keep the valve filled with oil. Always use original-specification seals when servicing.
