Key Technical Advantages (MCV Series Common)
1. Torque-Motor Actuated Double-Nozzle Flapper Valve Structure for High-Precision Control
MCV series PCP valves feature a torque-motor actuated, double-nozzle flapper valve configuration. The torque motor converts electrical input signals into precise mechanical displacement, producing differential output pressure proportional to the applied signal by varying the nozzle-flapper clearance. Compared to conventional solenoid designs, the torque motor delivers superior dynamic response frequency and lower hysteresis.
2. Single-Stage Stand-Alone Closed-Loop Pressure Control
MCV series PCP valves are single-stage, stand-alone closed-loop pressure control valves that use internal hydraulic pressure reactions to achieve closed-loop control characteristics. Precise closed-loop pressure control is achieved without external feedback elements, significantly simplifying the hydraulic system control architecture.
3. Perfect Integration with Danfoss Series 90 Pumps
MCV series PCP valves mount directly on the pump head of Danfoss Series 90 variable displacement piston pumps (90R/90L). They convert electrical signals into proportional pilot differential pressure to adjust pump swashplate angle and regulate pump displacement and output flow. The compact modular layout reduces external piping and fitting requirements.
4. Fast Response and High Repeatability
Both MCV110A1017 and MCV116A3102 feature ≤20 ms response time and ±1% repeatability. Fast response ensures timely pressure adjustment during sudden load changes, protecting equipment safety.
5. Wide Pressure Range and Flexible Adaptability
MCV110A1017 rated pressure covers 21–35 MPa. MCV116A3501 supports a typical pilot pressure of 17.2 bar with air flow of 550 L/min. The wide pressure and flow coverage flexibly adapts to diverse applications from small-to-medium equipment to large heavy-duty machinery.
6. Rugged Environmental Durability
MCV110A1017 offers optional IP65/IP67 protection. MCV116A3501 ambient operating temperature covers -40°C to +93°C. MCV116A3501 features a Weather-Pack connector for enhanced dust and moisture resistance. These products are suitable for diverse extreme climate conditions and demanding industrial environments.

Expert Maintenance Tips
1. Installation Guidelines
MCV series pilot valves mount directly on the pump head pilot manifold—pay special attention to alignment with locating pins during installation to prevent spool sticking due to misalignment.
Thoroughly clean the mounting surface and all ports before installation to prevent foreign particles from entering the pilot valve and causing nozzle blockage or flapper sticking.
MCV110A1017 features a 6-port design—verify correct port connections during installation.
2. Hydraulic Fluid Cleanliness
MCV series pilot valves incorporate precision nozzle-flapper mechanisms that are highly sensitive to fluid cleanliness.
Recommended fluid: Anti-wear mineral hydraulic oil.
MCV116A3501 ambient operating temperature range: -40°C to +93°C.
Install a return line filter with minimum 10 μm filtration rating.
3. Electrical Connection Specifications
MCV116G4204 features a 4-wire configuration. MCV116A3501 features a Weather-Pack connector.
Shielded cables are recommended for command signal connections to prevent electromagnetic interference affecting control precision.
4. Periodic Maintenance Inspection
Inspect the valve body for external oil leakage every 2,000 operating hours or at least annually.
Check electrical connectors for looseness, oxidation, or moisture ingress.
If response lag or reduced control precision is observed, first check system fluid cleanliness and pilot screens for blockage—nozzle-flapper mechanism contamination is the most common cause of performance degradation.
The torque motor assembly must not be disassembled by end users; any repairs should be performed by qualified hydraulic service professionals.
