Robust mechanical directional control valve featuring twin-pressure operation and spring centering. The symmetrical port design minimizes pressure drop (ΔP ≤0.15MPa at max flow) while maintaining precise mid-position shutoff. Optimized for high-cycle applications with its hardened stainless steel poppet and wear-resistant guide bushings.
- Clamping fixture sequencing in CNC machinery
- Pneumatic conveyor diverter systems
- Emergency stop circuits with manual override
- Automated assembly line tool changers
- Textile machinery tension control systems
Installation note:
Ensure exhaust ports remain unobstructed - minimum 10mm clearance recommended.
For vertical mounting, orient operator button upward. Use Loctite 545 on pipe threads.
Requires 5-10μm filtration (40μm max particulate).
