Key Materials and Components
▔▔
- Valve Body: High-density ductile iron (GGG40/GGG50) casting for superior structural rigidity and high burst pressure allowance.
- Spool & Sleeve Assembly: Hardened stainless steel (440C grade) with sub-micron surface polishing, ensuring micro-clearance, minimal internal leakage, and extreme wear resistance.
- Sealing System: Fluorocarbon rubber (FKM / Viton) seals as standard, suitable for synthetic fluid and wide temperature operations.
- Coil Housing & Drive Unit: IP67-rated sealed aluminum anodized housing with epoxy-encapsulated motor coils for harsh vibration and outdoor moisture protection.
Packaging and Transport Protection
▔▔
- Individual Unit Packaging: Each MGV Motor is encased in oil-resistant anti-corrosion VCI (Volatile Corrosion Inhibitor) packaging bags.
- Moisture & Shock Protection: Precision-cut high-density EPE foam inserts protect the motor housing, connectors, and precision surfaces during transport.
- Fixation & Stability: Rigid anti-vibration internal box placement prevents displacement or calibration shifts caused by impact.
- Bulk Transport: Heavy-duty, ISPM-15 compliant export plywood cases reinforced with steel strapping to withstand international maritime or air transport.
Applications
▔▔
- Plastic Injection Molding Machines: Used for real-time precise control of injection speed and multi-stage packing pressure profiles to prevent product flash and warp.
- Metal Die-Casting & Forging Presses: Applied in real-time shot cylinder closed-loop control to achieve ultra-fast, high-acceleration pressing cycles.
- CNC Bending & Metal Forming Equipment: Employed for synchronized axis position control of dual hydraulic cylinders to ensure high bending precision.
- Test Benches & Flight Simulators: Utilized in high-frequency dynamic loading actuators for real-time load simulation and movement control.

FAQ
▔▔Q1: How do I select the correct MGV Motor model for my machine?
A1: Model selection depends on your required system operating pressure, maximum fluid flow rate, response time, and signal protocol. You can check the Ordering Code table above or provide your system schematics to our technical engineers for assistance.
Q2: What is the recommended oil filtration level for the MGV Motor?
A2: Due to the high precision of the spool-and-sleeve clearance, oil cleanliness must meet ISO 4406 standard 16/14/11 or NAS 1638 Class 7 (filter rating β10 ≥ 75).
Q3: Which hydraulic fluid types are compatible with the MGV Motor?
A3: Standard units are compatible with mineral oil-based hydraulic fluids (HLP, HM). For synthetic ester or phosphate ester fluids, please specify upon ordering so we can supply FKM or specialized seals.
