MCV116G4201 MCV116G4204 MCV110A1017 Danfoss Pressure Control Pilot Valve 350 bar

Product Overview

The MCV series Pressure Control Pilot (PCP) valves are precision electro-hydraulic control components engineered by Danfoss (formerly Sauer-Danfoss) for the Series 90 variable displacement piston pumps. These valves are widely used for pump displacement control and pressure regulation in mobile machinery and industrial hydraulic systems.

The core technology of the MCV series is a torque-motor actuated, double-nozzle flapper pilot stage. The torque motor receives a DC milliamp current signal (typically 75–100 mA) and drives the flapper via electromagnetic torque, producing a differential pressure output proportional to the control signal. This pilot pressure directly actuates the servo piston of the Series 90 pump, enabling electro-hydraulic proportional pump displacement control.

The MCV series offers multiple models and configurations:

• MCV110A1017: MCV110 series PCP, single-stage standalone closed-loop pressure control valve

• MCV116A3101: MCV116 series PCP, Stage 14, coil resistance 23 Ω, rated current ±100 mA

Key Technical Advantages

1. Torque-Motor Actuation for High-Precision Electro-Hydraulic Proportional Control

The MCV series utilizes a torque motor as the electro-mechanical transducer. The torque motor receives a DC milliamp current signal (typically 75–100 mA) and drives the flapper via electromagnetic torque. Compared to conventional proportional solenoids, the torque motor delivers superior control precision, faster response, and lower hysteresis—the core technology enabling closed-loop pump displacement control.

2. Double-Nozzle Flapper Pilot Stage for Precise Differential Pressure Output

The MCV series features a double-nozzle flapper pilot stage. As the flapper deflects under torque motor actuation, the outlet pressures of the two nozzles change in opposite directions—one increasing while the other decreases—producing a differential pressure output proportional to the control signal. This differential pressure directly drives the servo piston of the Series 90 pump for precise pump displacement control.

3. Single-Stage Standalone Closed-Loop Control – No External Feedback Required

The MCV series is a single-stage, standalone, closed-loop pressure control valve. It uses internal hydraulic pressure reactions to achieve closed-loop control characteristics without external pressure sensors or additional feedback loops. This design significantly simplifies system integration and reduces total cost.

4. Rugged Construction for Harsh Operating Conditions

The MCV series is constructed from stainless steel or cast iron and withstands mobile equipment vibration and shock conditions. Design life is ≥10,000 hours or ≥10,000,000 cycles. Ambient operating temperature range -40°C to +93°C and oil temperature range -20°C to +107°C meet the most demanding global construction machinery requirements.

5. Broad Displacement Compatibility with Flexible Configurations

The MCV series is compatible with Danfoss Series 90 variable displacement pumps. Multiple MCV110 and MCV116 series variants, stages, and configurations support applications from 5–50 gpm pilot-operated flow control valves to variable pumps and motors.

6. 100% Direct Interchangeability and Simulated Condition Testing

The MCV series strictly adheres to Danfoss original mounting dimensions and interface standards. Valves of different configurations within the same series are physically and functionally identical, enabling 100% direct interchangeability without pump modification or system adjustment. Every unit undergoes 100% simulated operating condition bench testing prior to shipment.

• Mining Equipment: Hydrostatic drive systems for underground LHDs and mining trucks

Expert Maintenance Tips

1. Verify Model and Pump Compatibility Prior to Installation

The MCV series is a dedicated control valve for Series 90 variable displacement pumps. Confirm that the model matches the pump displacement and control requirements—MCV110 and MCV116 series correspond to different pump types and control configurations. Mismatched models will result in abnormal control characteristics and significantly impair system performance.

2. Electrical Wiring Precautions

The MCV series is driven by a torque motor requiring a DC milliamp current control signal (typical 75–100 mA). Coil resistance is approx. 23 Ω. High voltage or high current signals must never be applied, as this will damage the torque motor coils. Verify that the controller output signal type matches the valve specifications prior to wiring.

3. Oil Cleanliness Management

The MCV series pilot stage features extremely tight clearances (double-nozzle flapper gaps typically in the micron range) and demands high oil cleanliness. Recommended system cleanliness: ISO 4406 Class 18/16/13 or higher. Install high-precision filters (filtration rating ≤10μm) in the system return line and inspect filter elements regularly.

4. Installation Torque and Sealing

Use a torque wrench to tighten mounting bolts to the values specified in Danfoss technical manuals. Use OEM-specification O-rings for sealing—inspect seal condition prior to installation and replace if worn or damaged. Do not apply excessive sealant, as sealant debris may enter the valve body.

5. System Commissioning and Calibration

After replacing the MCV control valve, recalibrate the pump displacement control. Conduct preliminary commissioning at low pressure and low speed to verify that the proportional relationship between control signal and pump displacement output meets expectations. Gradually load to rated conditions while monitoring system response for smooth operation, oscillation, or hysteresis.

6. Periodic Maintenance and Inspection

Perform functional checks every 2,000 operating hours or annually, including: linearity verification between control signal and displacement output, response time testing, and leakage inspection. Design life is ≥10,000 hours or ≥10,000,000 cycles. If sluggish response, non-linear behavior, or increased leakage is observed, arrange for servicing or replacement.
