The HD4A220 features a balanced spool design with low starting pressure (0.15MPa) capability, making it ideal for low-pressure pneumatic systems. Its dual-chamber sealing structure ensures zero leakage during standby. The valve incorporates surge protection circuitry and is compatible with SMD mounting for automated assembly processes. Requires 5μm filtered dry air with ISO8573-1:2010 Class 3.4.3 air quality.
- High-speed sorting equipment with rapid cylinder cycling
- Plastic injection molding machine ejector systems
- Automated welding fixture clamping sequences
- Textile machinery thread tension control
- Beverage canning line pneumatic diverters
Installation guidelines:
Mount in vibration-free environment with ≤0.5mm alignment tolerance.
Maintain ≥15mm clearance on exhaust ports for proper venting.
Lubrication recommended every 5 million cycles using ISO VG32 turbine oil.
