High-flow directional control valve with modular design, featuring wear-resistant spool structure and dual-position memory function. The 3A220-08's large exhaust ports (M5x0.8) ensure rapid cylinder movement, while its anti-vibration design maintains stable operation in mobile machinery. Requires 5μm filtered compressed air with lubrication (ISO 8573-1 class 4).
- Automated assembly line cylinder sequencing
- Plastic injection molding machine clamp control
- Textile machinery pneumatic circuits
- Automotive welding fixture positioning
- Bottle filling station actuator control
Installation note:
For optimal performance, maintain ambient temperature below 60℃ and install shock absorbers when used in high-vibration environments. Lubricate pilot air with ISO VG32 turbine oil (1-2 drops/m³ air).
