High-flow mechanical selector valve with manual override capability, featuring a robust aluminum body with anti-corrosion treatment. The closed-center design prevents unintended actuator movement during system shutdown. Optimized flow paths reduce pressure drop by 18% compared to previous generations. Compatible with ISO VG32 hydraulic oil when using optional seals.
- Machine tool clamping/unclamping systems
- Plastic injection molding machine sequence control
- Automated assembly line tool changers
- Test bench pressure regulation stations
- Food processing pneumatic circuits (NSF-H1 grease compatible version available)
Installation guidelines:
Mount with 10mm clearance above for manual operation access.
Use M5 mounting screws with 0.49-0.69N·m torque.
Lubricate pilot ports with ISO VG32 oil if using pneumatic pilot control.
