I. Product Positioning & Core Functions
TheMCV110A1017is apressure control pilot valvefrom Danfoss (now Sauer-Danfoss) within its MCV series, designed for high-pressure hydraulic systems. Its core functions include:
1. Pressure Regulation & Control: Precisely adjusts system pressure via a pilot-operated structure, suitable for applications requiring stable pressure output (e.g., construction machinery, industrial equipment).
2. Pilot Control: Acts as a secondary control component, converting external signals (e.g., electric or manual) into hydraulic signals to drive main valve spool movement, enabling remote or automatic control.
3. Protection Function: Integrates overpressure protection to prevent system damage caused by excessive pressure.
II. Technical Specifications & Performance Metrics

Parameter Typical Value Notes
Rated Pressure 21–35 MPa (model-dependent) Must match the system’s maximum operating pressure.
Control Method Pilot-operated (electric/manual optional) Supports electric proportional control or manual emergency operation.
Port Configuration 6-port design Enables simultaneous control of multiple actuators (e.g., double-acting cylinders).
Response Time ≤20 ms Rapid response to pressure changes enhances system stability.
Repeatability ±1% High-precision control minimizes pressure fluctuations.
Protection Class IP65/IP67 (optional) Suitable for harsh environments (e.g., outdoor, dusty conditions).
III. Typical Application Scenarios
1. Construction Machinery
• Excavators: Controls hydraulic cylinder pressure for boom and arm movements, ensuring precise compound actions.
• Cranes: Regulates luffing mechanism pressure to prevent overloading.
2. Industrial Automation
• Injection Molding Machines: Manages clamping force for mold safety.
• Machine Tools: Adjusts hydraulic fixture clamping pressure.
3. Agricultural Machinery
• Combine Harvesters: Controls header height adjustment cylinder pressure.
4. New Energy Sector
• Wind Turbine Pitch Systems: Synchronizes pressure regulation for multiple blade hydraulic cylinders.
IV. Product Advantages & Differentiators
1. Modular Design
• The MCV series supports flexible combinations with functional modules (e.g., proportional valves, directional valves) to meet diverse needs.
2. High Reliability
• Dual control modes (electric + manual) ensure safe system degradation during failures.
3. Energy Efficiency
• Closed-loop control reduces overflow losses, lowering energy consumption.
4. Durability
• Built with high-strength materials and advanced sealing technology for high-pressure, high-frequency applications.
V. Selection & Installation Considerations
1. Pressure Matching
• Ensure the valve’s rated pressure ≥ the system’s maximum operating pressure, with a safety margin.
2. Flow Requirements
• Select valve port size based on actuator flow demands to avoid insufficiency or excess.
3. Control Signal Compatibility
• For electric control, verify signal type (e.g., 4-20mA, PWM) matches the controller.
4. Installation Environment
• Choose IP67 protection for outdoor or harsh environments and add dust covers if needed.
5. Maintenance & Upkeep
• Regularly inspect seals for wear and replace hydraulic fluid to maintain system cleanliness.
