High-performance general-purpose solenoid valve featuring dual-chamber diaphragm structure for stable switching under variable pressures. The copper-free aluminum alloy plunger ensures compatibility with cleanroom environments. Designed with surge protection circuitry for extended coil life (≥30 million cycles). Requires 5μm filtration with oil mist lubrication (ISO 8573-1:2010 Class 4.4.3).
- Plastic injection molding machine clamp controls
- CNC pneumatic tool changers
- Beverage filling line actuators
- Semiconductor wafer handling robotics
- Textile machinery tension control systems
Installation protocol:
Mount horizontally with arrow aligned to flow direction. Use flexible tubing
(≥300mm length) before/after valve to reduce vibration transfer. Perform
monthly manual cycling during standby periods exceeding 30 days.
