High-flow proportional control valve featuring low hysteresis design for precision fluid regulation. The hardened aluminum alloy body with anodized treatment resists chemical corrosion, while the dual-coil structure enables continuous duty operation. Requires 5μm filtered compressed air with oil mist (ISO 8573-1 Class 3).
- Plastic injection molding machine clamp control
- Automated bottling line pressure sequencing
- Semiconductor wafer handling vacuum/pressure systems
- Textile machinery air-jet loom nozzle control
- Food processing pneumatic actuator arrays
Installation protocol:
Mount with vibration-damping gaskets in high-shock environments.
Maintain 15° maximum angular deviation from vertical axis.
Pipe connections must follow torque specs (15-20N·m for PT threads).
