High-flow proportional control valve with center-blocking function, featuring low hysteresis design for precision directional control in pneumatic systems. The hardened aluminum alloy body with anodized treatment ensures corrosion resistance in humid environments. Requires 5μm filtered lubricated air (ISO 8573-1 class 4) with oil mist concentration 1/30000.
- Multi-position cylinder control in automated assembly lines
- Clamping sequence control in injection molding machines
- Pneumatic press brake systems for metal forming
- Packaging machine indexing mechanisms
- Automotive tire assembly equipment
- Textile machinery tension control systems
Installation guidelines:
Maintain horizontal mounting orientation (±15° tolerance). Allow ≥20mm clearance
around valve body for heat dissipation. Use flexible tubing to prevent mechanical
stress. Perform monthly manual cycling during standby periods exceeding 30 days.
