Danfoss MCV Series Control Valve | MCV116A3501 MCV116G4204 MCV110A1017 | Sauer-Danfoss Replacement

The MCV Series proportional control valves from Chengyuan Hydraulic are high-precision components fully compatible with Sauer-Danfoss industrial standards. These valves are essential for controlling the displacement of hydrostatic pumps (such as the 90 Series) or motors, providing precise regulation of speed, direction, and torque via electronic signals. For core models like MCV116A3501 and MCV116G4204, we utilize reinforced electromagnetic pilot stages and low-hysteresis spool designs. Every MCV valve undergoes 100% dynamic response testing under simulated conditions to ensure minimal linear deviation between control signals and output flow, guaranteeing 100% original-place interchangeability.

Technical Specifications :

• Series Model: MCV110 / MCV116 / MCV105 Series

• Control Type: Electro-hydraulic Proportional

• Rated Pilot Pressure: 15 – 25 bar (depending on code)

• Supply Voltage: 12V DC / 24V DC

• Max Pilot Flow: 1.5 – 2.8 L/min

• Enclosure Rating: IP67

• Mounting Interface: Standard 4-bolt interface (compatible with Danfoss pump/motor flanges)

• Coil Resistance: 12Ω – 30Ω (differentiated by suffixes A/G/C)

Key Technical Advantages:

• Ultra-Low Hysteresis Pilot Stage: The heart of the MCV series is its high-performance electromagnetic pilot system. By optimizing magnetic permeability and sliding surface friction, we maintain hysteresis within 1.5%, providing smooth and jitter-free operation.

• Thermal Stability under Full Load: Designed for intensive mobile machinery applications, the MCV series features a balanced heat dissipation design. The gain curve between control current and pilot pressure remains consistent even during significant oil temperature fluctuations.

• Precision Centering Mechanism: Spool return springs are crafted from fatigue-resistant alloy steel, ensuring the deadband remains constant after hundreds of thousands of cycles, preventing zero-point drift or sluggish actuator response.

• High Environmental Resilience: To withstand harsh agricultural and construction environments, the electronic sections are fully encapsulated. This provides superior resistance to vibration, salt spray, and EMI, ensuring reliable electro-hydraulic logic.

Application Areas:

• Road Rollers & Pavers: Controlling pump displacement for smooth acceleration and braking.

• Harvesters: Regulating proportional speed for ground drive and reel drive circuits.

• Concrete Machinery: High-precision speed control for pump trucks and mixer drums.

Expert Maintenance Tips:

• Pilot Supply Pressure Verification: Before installation, verify that the pilot oil pressure from the pump meets the MCV specifications (typically around 18 bar). Insufficient pressure will prevent the spool from reaching full stroke, limiting maximum displacement.

• Coil Insulation Checks: In humid conditions, regularly inspect the waterproof gaskets on electrical connectors. Moisture ingress can cause micro-shorts that interfere with proportional signals, leading to irregular machine behavior.

• Charge Pressure Coordination: The performance of the MCV valve relies heavily on the quality of the charge pressure system. Ensure charge pump filters are replaced on schedule, as the pilot stage is highly sensitive to fine contaminants.
