Industrial-grade solenoid valve featuring dual-chamber design for enhanced flow efficiency and reduced pressure loss. The AI suffix indicates anti-vibration optimization with stainless steel plunger guide and shock-resistant coil assembly. Requires ISO 8573-1:2010 Class 3.4.2 compressed air (max 5μm particle size, oil content ≤1mg/m³). Compatible with vacuum applications down to -95kPa.
- High-cycle automation: Robotic tool changers (≥5 million cycles rating)
- Low-power environments: Solar-powered irrigation systems
- Harsh conditions: Foundry equipment with intermittent water splash
- Precision medical: Dental chair pneumatic controls
- Food processing: Modified atmosphere packaging (MAP) machines
Installation Protocol:
Mount in any orientation (ISO standard compliant) but avoid downward-facing exhaust ports in dusty environments. Maintain 15mm clearance around coil for heat dissipation. Use flexible tubing to prevent mechanical stress on valve body.
Critical Note:
Not compatible with phosphate ester-based lubricants. For continuous operation above 60℃, derate maximum pressure by 0.15MPa per 10℃ increment. Always install upstream 40μm filter.
