High-flow compact solenoid valve featuring dual-chamber design for enhanced pressure balancing. The 3V31008NCBI-W incorporates a copper-free aluminum alloy piston and gold-plated terminals for corrosion resistance in humid environments. Its low-hysteresis coil (Class F insulation) ensures stable operation with 100% ED (continuous duty) capability. Requires 5μm filtration with oil mist lubrication (ISO VG32 recommended).
- Pneumatic cylinder sequencing in assembly robots
- Vacuum generator control for material handling systems
- Coolant line switching in CNC machining centers
- Packaging machine clamp/unclamp operations
- Medical gas distribution equipment
Operational note:
Maintain air quality per ISO 8573-1:2010 Class 3.4.2 (max particle size 5μm,
pressure dew point 3℃ below minimum operating temperature). For horizontal
piping, install valve with exhaust port downward to prevent condensate ingress.
