Airtac 3A100 Pneumatic Control Valve 3A120-M5
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.

Mechanically actuated pneumatic valve optimized for harsh environments, featuring dual O-ring seals and anti-vibration stem design. The angled port configuration (120° between inlet/outlet) enables compact plumbing layouts. Requires manual push-button operation or mechanical linkage integration.
- Emergency stop systems in CNC machinery
- Pneumatic clutch engagement in conveyor systems
- Safety door interlocks for injection molding machines
- Manual override stations in automated production lines
- Agricultural equipment hydraulic pilot controls
Maintenance Protocol:
Lubricate actuator shaft with PTFE-free grease every 50,000 cycles.
Use thread sealant on M5 ports when operating above 0.7 MPa.
Avoid side-loading forces exceeding 15N on actuator button.
