- Category:
- Pneumatic Control Valves
- Brand:
- AIRTAC
- Series:
- HD4A
The AIRTAC HD4A series represents a premium line of 4-way pneumatic directional control valves engineered for industrial automation systems. Featuring poppet-valve construction with enhanced flow paths, these valves deliver:
- High flow capacity (Cv up to 4.8)
- Low power consumption (0.5W typical)
- Multiple actuation options: solenoid, mechanical, pneumatic pilot
- Compact modular design with ISO 15407-1 compliant interfaces
- Operational pressure range: 0.15-0.7 MPa
- Port sizes: 1/4" to 1" NPT/BSPP
- Fluid compatibility: Filtered dry air (ISO 8573-1:2010 Class 3.4.2)
With IP65 protection rating and -5°C to 80°C operational temperature range, the HD4A series excels in demanding industrial environments requiring precision flow control and high cycling frequency.

Installation guidelines:
Mount in vibration <5m/s² environments. Use M3x10 screws (torque ≤0.4Nm).
Maintain 15mm clearance below valve for exhaust dispersion. Lubricate with ISO VG32
turbine oil if operating below -10℃. Replace seals after 5 million cycles.
