I. Product Overview
This product series comprises Danfoss (formerly Sauer-Danfoss) Electric Displacement Control (EDC) modules and Pressure Control Pilot (PCP) valves—the core components of displacement control systems for Danfoss S90 series variable piston pumps and S42 hydrostatic transmissions. The KVEB series represents Danfoss’s next-generation electric displacement control solution for S90 series pumps, designed as a direct replacement for the previous MCV111 and KVEA series control modules.
Product lineup overview:
KVME11201: 42 Series EDC proportional servo valve with MS connector (DE1A2)
KVEBB0702: EDC control module specifically designed for S90 series 75cc displacement piston pumps, dual coil configuration, MS connector
MCV116G4201: Pressure Control Pilot valve (PCP Type 4), the core pilot control component of the EDC module
KVEBB1402: EDC control module specifically designed for S90 series 130cc displacement piston pumps, dual coil configuration, integrated with MCV116G4201 pilot valve

III. Key Technical Advantages
1. Torque-Motor + Double-Nozzle Flapper Pilot Technology (MCV116G4201)
The MCV116G4201 Pressure Control Pilot valve features torque-motor actuation with a double-nozzle flapper configuration, precisely converting electrical input signals into proportional differential pressure output. This design delivers exceptional pressure-to-current linearity and fast response characteristics, making it the core technology enabling precise displacement control for S90 series pumps.
2. Single-Stage Closed-Loop Control – No External Feedback Required
The MCV116G4201 is a single-stage, standalone closed-loop pressure control valve that achieves its closed-loop characteristics using internal hydraulic pressure reactions. This eliminates the need for external pressure sensors or complex closed-loop control circuits, significantly simplifying system architecture and improving overall reliability.
3. Two-Stage Electrohydraulic Control Architecture (KVEB Series)
The KVEB series EDC is a two-stage electrohydraulic pump stroke control: the first stage, the MCV116 Pressure Control Pilot (PCP), produces a differential output pressure proportional to the applied electrical signal; the second stage uses this differential pressure to drive its unique spool arrangement and port oil to the pump servo cylinders. The second-stage spool configuration allows a null deadband (for machine safety) in the pump’s output while maintaining optimum dynamic response to control commands.
4. 100% Direct Interchangeability & OEM-Standard Manufacturing
All models are manufactured to strict Danfoss/Sauer-Danfoss OEM specifications, ensuring 100% mechanical and hydraulic interchangeability with original parts. The KVEB series incorporates design enhancements in the control spool and feedback mechanism, as well as nozzle area/clearance revisions, while maintaining form and fit—allowing direct replacement of previous KVEA and MCV111 series control modules.
5. Dual Coil Redundancy & Multiple Current Range Options
KVEB series EDC features a dual coil torque motor configuration that can sum two command sources, providing control redundancy. Should one coil fail, the other coil can maintain basic control functionality. The product supports multiple current ranges including 14-85 mA (dual coil) and 4-20 mA (single coil, Intrinsically Safe), accommodating various control system requirements.
6. Harsh Environment Resistance & Long-Term Stability
KVEB series features a standard silicone oil filled torque motor, environmentally sealed first/second stage interface, and has undergone full environmental testing. It also offers minimum long-term null shift, ensuring reliable long-term operation in demanding mobile machinery environments.

V. Expert Maintenance Tips
1. Verify Model & Displacement Matching (★★★★★)
KVEBB0702 is specifically designed for S90 series 75cc displacement piston pumps
KVEBB1402 is specifically designed for S90 series 130cc displacement piston pumps
KVME11201 is specifically designed for S42 hydrostatic transmissions
Confirm pump displacement matches the module model before installation. Mismatched pairing will result in displacement control errors and may cause severe pump damage.
2. KVEB vs. MCV/KVEA Compatibility Considerations (★★★★★)
The KVEB series is a direct replacement for KVEA and MCV111. Important considerations:
KVEB coil resistance: 16Ω and 20Ω; MCV coil resistance: 25Ω and 25Ω
When mixing KVEB and MCV in the same vehicle propel application with parallel electrical connection, the KVEB pump will stroke approximately 25% ahead of the MCV
A series electrical connection is recommended to ensure all EDCs receive identical current
When possible, use the same type of EDC for all pumps in the system
3. Oil Cleanliness Management (★★★★★)
KVEB series EDC control modules contain pilot valve spools and nozzle-flapper structures that are highly sensitive to oil contamination. Maintain system oil cleanliness at ISO 4406 16/14/12 or better. Use 10μm or higher-precision return filters and inspect filter elements regularly.
4. Control Current Range Verification
KVEBB0702 and KVEBB1402 operate within a 14-85 mA control current range
KVME11201 operates on standard 42 Series EDC current control
Calibrate control current zero point and full scale after installation to ensure displacement control accuracy. Exceeding the control current range may cause coil overheating or spool sticking.
5. Electrical Connection & Shielding
KVME11201 features an MS connector (DE1A2)
KVEBB0702 and KVEBB1402 feature MS connectors
Control signals are DC milliampere current signals—sensitive to electromagnetic interference
Use shielded twisted-pair cables for control wiring, with shield grounded at one end
6. Installation Torque Specifications
When mounting EDC control modules to the pump body, tighten mounting bolts to Danfoss recommended torque. Excessive torque may deform the module housing and affect internal spool movement; insufficient torque may cause seal failure and external leakage. Different displacement pumps require corresponding mounting kits.
7. Storage Environment
Recommended storage temperature: -40°C to +85°C. Avoid impact loads on the module body during installation. Handle with care to prevent drop damage to pilot valve components.
