High-flow solenoid valve engineered for industrial automation systems requiring rapid cycling and fail-safe open operation. Features brass alloy body with electroless nickel plating for chemical resistance. Optimized spool design reduces pressure drop by 18% compared to previous generations. Requires ISO 8573-1:2010 Class 3 compressed air (max 5mg/m³ oil content).
- Plastic injection molding machine ejectors
- CNC pneumatic tool changers
- Beverage filling line actuators
- Lithium battery production equipment
- Semiconductor wafer handling robots
- Textile machinery tension control systems
Installation guidelines:
Mount with M5 mounting brackets (included). Maintain minimum 50mm clearance below valve for condensate drainage. Use copper-free anti-seize compound on threads. For horizontal mounting, orient coil connector upward to prevent debris accumulation.
Critical note:
Not compatible with phosphate ester fluids or ammonia-based lubricants. Requires 2-3 second power-on delay during cold starts below 0℃. Perform manual cycling weekly if idle for extended periods.
