Airtac 3A300 Pneumatic Valve 3A310-10NC
1. Spool-type structure with superior sealing performance and instant response characteristics;
2. Double pilot operation enables position memory function;
3. Precision-machined internal bores ensure minimized friction resistance, low actuation pressure (0.15MPa), and extended service life;
4. Maintenance-free operation without lubrication requirements;
5. Multiple mounting orientations (X/Y/Z axes) for flexible installation;
6. Compatible with manifold base integration for space-optimized valve arrangements.

Robust pilot-operated valve featuring dual-pressure control capability and high flow efficiency. The optimized spool design reduces air consumption by 15% compared to previous generations. Requires 0.3MPa minimum pilot pressure for reliable actuation, with built-in silencer reducing exhaust noise to ≤72dB(A).
- Pneumatic clamping systems in CNC machinery
- Automated assembly line actuators
- Plastic injection molding machine controls
- Material handling cylinder sequencing
- Textile machinery tension control systems
Maintenance protocol:
Lubricate pilot piston quarterly with ISO VG32 turbine oil.
Avoid mounting near high-frequency vibration sources (>50Hz) to prevent spool oscillation.
