Airtac 3A100 Pneumatic Control Valve 3A120-06
A cropped merino wool cardigan taken up a notch, thanks to the flecks of metallic thread throughout. We love it even more paired with the matching sweater-pants.
2. Double pneumatic pilot control features inherent memory function;
3. Precision-engineered internal bore minimizes friction resistance, enabling low actuation pressure and extended service life;
4. Maintenance-free operation without lubrication required;
5. Supports versatile mounting orientations for simplified installation and operation;
6. Compatible with modular valve base integration to optimize space utilization.

High-flow directional control valve with center-block function, featuring dual-pressure operation capability. The optimized spool structure reduces air consumption by 15% compared to previous generation models. Requires 5μm filtered lubricated air (ISO 8573-1 class 4).
- Clamping mechanisms in CNC machining centers
- Rotary indexing tables with pneumatic braking
- Material handling systems requiring mid-position lock
- Plastic injection molding machine ejectors
- Automated assembly line tool changers
Installation guidelines:
Mount with vibration-damping brackets in high-cycle applications (>5Hz).
Maintain 1.5x port diameter clearance between valve and adjacent components.
Lubricate with ISO VG32 turbine oil if using non-lubricated air.
