High-flow directional control valve with dual-coil configuration for precise pneumatic circuit switching. Features aluminum alloy body with hard anodized surface treatment for enhanced corrosion resistance. The low-hysteresis design ensures stable operation in high-cycle applications (up to 5 million cycles). Requires ISO 8573-1:2010 Class 3 compressed air (max 5mg/m³ oil content).
- Pneumatic cylinder sequencing in automated assembly lines
- Clamping control for CNC machining centers
- Material handling systems (rotary actuators control)
- Textile machinery thread tension regulation
- Bottle cap tightening mechanisms in beverage production
Installation Guidelines:
Mount using M4 screws with 45mm mounting pitch. Maintain minimum 30mm clearance below exhaust ports for unimpeded airflow. Use locknuts (included) to prevent vibration-induced loosening. Always install downstream air filter with 5μm rating.
Critical Note:
For DC models, ensure correct polarity (+/- markings). Continuous energization should not exceed 85% duty cycle. When using AC coils, install surge suppression modules for electrical noise reduction.
