MCV116F3118 Danfoss Pressure Control Pilot Valve

Product Overview

The MCV116F3118, MCV116A3204, MCV116A3501, MCV116G4204 and MCV116G4201 belong to the Danfoss (formerly Sauer-Danfoss) MCV116 series of Pressure Control Pilot (PCP) valves. These torque-motor actuated, double-nozzle flapper valves convert an electrical input signal into a proportional hydraulic differential pressure output for controlling pilot-operated pumps, motors and main spool valves. Fully interchangeable with original Danfoss MCV116 units, every valve undergoes 100% simulated operating-condition testing for precise electro-hydraulic control in construction, agricultural and material-handling systems.

Technical Specifications

Key Technical Advantages

1. Precise electro-hydraulic conversion: Torque-motor and double-nozzle flapper design produces differential pressure proportional to the electrical signal with high accuracy.
2. Closed-loop pressure feedback: Internal hydraulic pressure feedback provides stable scale factor with minimal influence from supply pressure variations.
3. High interchangeability: Identical interfaces and performance to original Danfoss MCV116 series enable direct drop-in replacement.
4. 100% functional verification under simulated conditions: Every unit is fully tested across electrical signal-to-differential pressure characteristics before shipment, ensuring long-term reliability.

Application Areas

• Pilot control of variable-displacement pumps and motors
• Pilot stage for proportional main spool valves on construction machinery
• Electro-hydraulic systems on agricultural and material-handling equipment
• Closed-loop pressure control circuits
• Systems requiring electrical-to-hydraulic differential pressure conversion

Expert Maintenance Tips

Ensure clean ports and tighten to the specified torque. Maintain fluid cleanliness at ISO 4406 18/15 or better. Observe polarity and current limits during electrical connection. Periodically check null and proportional characteristics. If null drift or abnormal output occurs, first inspect fluid contamination and filters. For long-term storage keep the valve filled with oil. Always use original-specification seals when servicing.
