High-flow solenoid valve with direct-acting mechanism for reliable operation in low-pressure systems. Features brass port adapters for corrosion resistance and optional LED indicator. Requires 5-50μm filtered compressed air with lubrication (ISO8573-1 class 4-4-3). Compatible with vacuum applications when using special seals.
- Automated assembly line actuators
- Textile machinery air control systems
- Semiconductor wafer handling equipment
- Commercial coffee machine pneumatics
- Electric vehicle battery cooling systems
- Plastic injection molding machines
Installation guidelines:
Mount in vibration-free environment using M4 screws (max torque 1.2N·m).
Maintain minimum 15mm clearance above for heat dissipation.
Use 2mm Allen key for manual override operation.
Critical note:
Not compatible with phosphate ester fluids.
Cycle life exceeds 10 million operations when operated within
≤2Hz frequency with proper maintenance.
