High-flow 5/3-way solenoid valve designed for complex pneumatic circuits requiring intermediate position control. Features brass body with hard anodized aluminum core tube for enhanced corrosion resistance. The dual coil design allows latching function for energy-saving operation. Includes manual override and position-indication LED (optional). Requires 5μm filtered lubricated air (ISO8573-1 class 4).
- Automated clamping systems with mid-position safety lock
- Plastic injection molding machine actuators
- Textile machinery tension control systems
- Automotive tire assembly line equipment
- Bottle cap threading machines
- CNC tool changers requiring position memory
Installation guidelines:
Mount horizontally with coil axis vertical. Maintain minimum 15mm clearance
from adjacent components. Use anti-vibration washers in high-shock environments.
For continuous operation, keep ambient temperature below 60℃.
Critical note:
Do NOT use silicone-based lubricants. Cycle rate must not exceed
80% of maximum rated frequency (5Hz) for extended service life.
