WMME Type Solenoid Directional Valve with Auxiliary Handle: Detailed Specifications
1. Core Parameters & Structure
• Model Definition: WMME Type, a direct-operated solenoid directional valve equipped with an auxiliary handle (emergency handle) for manual override.
• Technical Specifications:
• Operating Pressure: Max. 31.5 MPa (315 bar), suitable for high-pressure hydraulic systems.
• Port Standards: NG6 (ISO 4401) and CETOP 3, compatible with mainstream hydraulic piping.
• Temperature Range: -40°C to 120°C, adaptable to extreme environments.
• Filtration Requirement: 25μm or finer filter mesh to ensure internal cleanliness.
• Electrical Characteristics: Minimum operating voltage at 90% of rated voltage; supports DC/AC power supply (specific voltages depend on model variants).
• Materials & Processes: Cast valve body with corrosion-resistant surface treatment; internal seals compatible with mineral oil, eco-friendly hydraulic oil, and synthetic fluids.
2. Functional Features
• Solenoid Control: Electromagnetically driven spool shifting for automatic hydraulic circuit switching.
• Auxiliary Handle: Manual operation via emergency handle in case of power failure or malfunction, ensuring system safety.
• Applications: Widely used in industrial hydraulic equipment (e.g., machine tools, construction machinery), automated production lines, and scenarios requiring redundant control.
4. Selection & Customization
• Optional Configurations: Customizable valve body materials (e.g., stainless steel), sealing materials (e.g., NBR, Viton), and electrical interfaces (e.g., DIN EN175301-803).
• Integrated Components: Often integrated with hydraulic manifolds, solenoid coils, and sensors to form complete hydraulic control systems.
5. Installation & Maintenance
• Installation Requirements: Must be installed in a clean, dry environment to prevent contaminants from entering the valve; electrical connections must comply with explosion-proof area regulations.
• Maintenance Recommendations: Regularly inspect seal wear, clean filter screens, and test manual override functionality.
