High-flow directional control valve with dual-pressure pilot design, featuring brass alloy body for corrosion resistance and anti-vibration stability. The optimized spool structure ensures ≤0.1MPa minimum operating pressure difference. Includes manual override button for emergency operation and status indication LED (DC models only). Requires 5μm filtered compressed air with ISO 8573-1:2010 Class 4 air quality.
- Pneumatic cylinder sequencing in automated assembly lines
- Clamping/unclamping systems in CNC machining centers
- Material handling equipment (stacker cranes, conveyor diverters)
- Plastic injection molding machine core-pull mechanisms
- Test bench pressure cycling systems
Installation guidelines:
Mount horizontally with pilot ports facing upward. Maintain 20mm clearance
below valve for maintenance access. Use copper-based anti-seize compound
on port threads. Lubricate air supply with ISO VG32 turbine oil mist
(1:30,000 ratio) for optimal seal life.
