Product Overview
▔▔The Parker ME Series represents a premium line of pilot-operated proportional directional control valves engineered for high-precision dynamic hydraulic applications. Positioning itself as a flagship series within Parker's advanced electro-hydraulic control lineup, the ME Series integrates standard proportional solenoid technology with integrated electronics (or external drive cards) to deliver smooth, accurate control of hydraulic oil flow direction and velocity.

Configuration Options
▔▔- Valve Structure: Two-stage design consisting of a high-response proportional pilot stage and a spool-type main stage valve body.
- Control Modes: Integrated onboard electronics (OBE) with analog voltage/current interface, CANopen fieldbus interface, or EtherCAT digital communication options.
- Feedback Systems: Linear Variable Differential Transformer (LVDT) position sensor attached directly to the main spool for high-resolution spool position feedback.
- Flow Configurations: Symmetric (1:1) and asymmetric (2:1 / progressive) spool notch geometries to match asymmetric cylinder areas.
- Port Interfaces & Mounting: Subplate mounting compliant with ISO 4401 / DIN 24340 standards (ISO 4401-03, 05, 07, 08 depending on frame size).
- Electrical Connections: 6-pin + PE main connector (MIL-C-5015) or M12 8-pin industrial electrical connector.
Key Materials and Components
▔▔
- Main Spool & Sleeve: Hardened stainless steel with specialized anti-wear surface treatment to minimize friction, resist contamination wear, and eliminate stiction.
- Main Valve Body: High-density ductile iron casting (GGG40/60) engineered for high burst pressure resistance and minimal internal deformation under full system pressure.
- Primary Seals: Fluorocarbon (FKM / Viton®) standard seals providing broad thermal resistance and chemical compatibility with mineral oils, synthetic esters, and fire-resistant fluids.
- LVDT Sensor Housing: Hermetically sealed stainless steel housing preventing fluid intrusion, electromagnetic interference, and mechanical vibration degradation.
Packaging and Transport Protection
▔▔
- Industrial Protection: Each valve is individually sealed in a heavy-duty, anti-static VCI (Vapor Corrosion Inhibitor) polybag to prevent atmospheric moisture oxidation.
- Shock Absorption: Secured in custom-molded high-density EPE foam cradles inside reinforced double-wall corrugated cartons to prevent impact damage during transit.
- Port Protection: All hydraulic ports are fitted with heavy-duty plastic plug caps to keep internal flow passages clean and free from contamination.
- Bulk Shipping: Multiple units are palletized on heat-treated ISPM-15 compliant wooden pallets, shrink-wrapped, and bound with high-tensile strapping for export transportation.
Applications
▔▔- Plastic Injection Molding Equipment: Provides closed-loop feedback control over injection speed profile, cavity pressure transition, and clamp positioning during high-speed molding cycles.
- Metal Die-Casting & Forging Presses: Regulates real-time acceleration and high-speed shot cylinder velocity profiles to optimize metal structural density and minimize flash.
- Precision Metal Bending & Shearing Machines: Controls synchronized movement of dual hydraulic cylinders to maintain precise ram parallelism and bending angle accuracy.
- Hydroelectric Turbine Control Systems: Regulates turbine guide vane positioning and runner blade actuation for accurate grid frequency matching under fluctuating loads.

FAQ
▔▔Q1: How do I verify the correct Parker ME model code for my replacement requirement?
A: Check the metal nameplate located on the side of the main valve body. Provide us with the full ordering code (e.g., ME16C35D01N10) and serial number. If the label is unreadable, send us photos of the mounting pattern, electrical connector layout, and fluid ports.
Q2: What fluid cleanliness level is recommended for the Parker ME proportional valve?
A: Due to the tight tolerances of the proportional pilot stage and main spool assembly, fluid cleanliness must meet or exceed ISO 4406 rating 18/16/13 (NAS 1638 Class 7). We recommend installing a high-pressure inline filter with a filtration rating of ≤ 10 µm absolute (β10 ≥ 75).
Q3: What type of hydraulic oil is compatible with standard Parker ME series valves?
A: Standard units fitted with FKM (Viton) seals are fully compatible with mineral-based hydraulic oils (HL, HLP), synthetic esters (HEES), and water-glycol fluids (HFC). For special fluid requirements, please consult our engineering team prior to ordering.
