Airtac 5A Pneumatic Control Valve 5A21008
2. 3-position pneumatic valve offers three center position functions (exhaust blocked, pressure retained, or exhaust center);
3. 2-position double pilot-operated valve features memory function to retain the last control state;
4. Precision-machined internal bore reduces friction resistance, enabling low actuation pressure and extended service life;
5. Oil-free lubrication design eliminates the need for external lubrication;
6. Modular design allows integration with manifold bases to save installation space;

High-flow directional control valve with symmetrical internal flow paths, optimized for bidirectional cylinder control. Features dual-pressure capability and low pilot consumption design. The aluminum alloy body with hard anodized finish resists chemical corrosion. Requires 5μm filtered/dried air with ISO 8573-1:2010 Class 3.2.4 air quality.
- Industrial automation sequencing systems
- Plastic injection molding machine clamp control
- Automotive assembly line tooling actuators
- Textile machinery tension control systems
- Palletizing robot end-effector controls
Installation guidelines:
Mount with manifold base (e.g., 5M-210 series) for optimal performance.
Maintain 15mm clearance below valve for heat dissipation. Lubricate with ISO VG32
turbine oil if air line lubrication is used. Avoid side-loading during tubing connection.
