MCV116F3118 Danfoss Pressure Control Pilot Valve PCP

Product Overview

The MCV116, MCV116F and MCV116F3118 belong to the Danfoss (formerly Sauer-Danfoss) MCV116 series of Pressure Control Pilot (PCP) valves. These are torque-motor actuated, double-nozzle flapper valves that function as single-stage, stand-alone closed-loop pressure control devices. They generate a differential output pressure proportional to the applied electrical input signal and are designed to pilot proportional main spool valves, variable-displacement pumps and motors, and other differential-pressure actuated devices. Fully interchangeable with original Danfoss MCV116 units, every valve undergoes 100% simulated operating-condition testing for reliable performance in construction, agricultural, material handling, marine, mining and industrial electro-hydraulic systems.

Key Technical Advantages

1. Closed-loop differential pressure control: Internal hydraulic pressure feedback enables precise single-stage closed-loop operation, delivering output differential pressure accurately proportional to input current.
2. Torque-motor double-nozzle flapper design: Fast response and good contamination tolerance, engineered to withstand mobile equipment vibration and shock.
3. True interchangeability and versatility: Identical interfaces and performance to original Danfoss MCV116 series enable direct drop-in replacement; suitable for piloting proportional valves, pumps and motors.
4. 100% functional verification under simulated conditions: Every unit is fully tested across current-pressure characteristics before shipment, ensuring consistency and long-term reliability.

Application Areas

• Electro-hydraulic control systems on construction and agricultural machinery
• Pilot control of proportional valves on material handling equipment
• Marine and mining hydraulic systems
• Pilot control of industrial variable-displacement pumps and motors
• Electro-hydraulic servo systems requiring differential pressure pilot signals

Expert Maintenance Tips

Ensure supply pressure is within the recommended range and return pressure remains below 13.8 bar. Use hydraulic fluid compatible with Viton/fluorosilicone seals and maintain cleanliness at ISO 4406 18/15 or better. Observe correct electrical polarity and current limits to avoid coil damage. Periodically check null offset and adjust with the proper tool if needed. If output pressure is abnormal, first inspect fluid contamination and pilot filtration. For long-term storage keep the valve filled with oil and cycle periodically. Always confirm the specific variant scale factor and connection type before replacement.
