2. Key Features and Technical Advantages
2.1. Compact and Modular Design
• Single-Piece Body: Reduces installation complexity and leakage risks.
• Stackable Modules: Supports customization with additional functions (e.g., shuttles, check valves, flow regulators) via modular expansion.
• Lightweight Construction: Aluminum or stainless steel body for corrosion resistance and reduced weight.
2.2. Precision Control and Performance
• High Flow Capacity: Rated flows up to2,000 Nl/min(depending on port size and spool type).
• Adjustable Spool Functions:
• 5/2-Way (Double Acting): For bidirectional cylinder control.
• 3/2-Way (Single Acting): For spring-return cylinders or vacuum applications.
• Custom Configurations: Tandem, latching, or proportional control available.
• Multiple Actuation Methods:
• Manual Lever: Spring return or detent-style for sustained positioning.
• Solenoid-Operated: 12V/24V DC or 110V/220V AC for automated control.
• Mechanical Pilot: For direct linkage to moving parts (e.g., cams, rollers).
• Air Pilot: Remote operation for complex systems.
2.3. Durability and Robust Construction
• High-Quality Materials:
• Anodized aluminum or stainless steel body for corrosion resistance.
• Hardened spool and sleeve for extended wear life.
• Advanced Sealing Technology:
• Low-friction, high-temperature-resistant seals (NBR, FKM, or PTFE).
• Anti-extrusion rings to prevent seal failure under high pressure.
2.4. Safety and Protection Features
• Integrated Exhaust Silencers: Reduces noise during valve operation.
• Anti-Cavitation Design: Minimizes wear and noise in high-flow applications.
• Overpressure Protection: Optional pressure relief valves to prevent system damage.

6. Selection and Installation Guide
6.1. Selection Criteria
• Load Requirements:
• For dynamic loads (e.g., robotic arms), choose a high-flow, quick-response valve.
• For static loads (e.g., clamping), a lower-flow, precise-control valve may suffice.
• Actuation Method:
• Manual for simple, infrequent operations.
• Solenoid for automated or remote control.
• Mechanical pilot for direct linkage to moving parts.
• Environmental Conditions:
• For washdown or corrosive environments, select stainless steel or IP69K-rated models.
6.2. Installation Tips
• Orientation: Install horizontally to prevent air traps and ensure proper valve operation.
• Piping: Use high-quality, flexible hoses to minimize vibration and stress on the valve.
• Filtration: Maintain air quality (ISO 8573-1 Class 5 or higher) to prevent spool sticking or seal damage.

7. Maintenance and Troubleshooting
7.1. Routine Maintenance
• Visual Inspection: Check for leaks, corrosion, or loose fittings.
• Seal Replacement: Replace seals every 2–3 years or after significant wear.
• Filter Cleaning: Clean or replace pneumatic filters regularly.
7.2. Common Faults and Solutions
【表格】
Fault Symptom Possible Cause Solution
Valve Not Responding Solenoid failure, low voltage Replace solenoid, check power supply
Internal Leakage Worn seals, spool damage Replace seals or spool assembly
