High-flow directional control valve featuring dual redundant seals and surge protection circuitry. Optimized for multi-cylinder sequencing with its 5-way configuration, supporting both pressure and exhaust center positions. The aluminum alloy body with hard anodizing ensures corrosion resistance in humid environments. Requires 5μm filtration (ISO 8573-1:2010 Class 3-4-2) with oil mist lubrication (ISO VG32 recommended).
- Automated assembly line clamping systems
- Plastic injection molding machine ejectors
- Bottle blowing machine air distribution
- CNC tool changer mechanisms
- Automotive paint shop pneumatic actuators
Installation guidelines:
Mount with vibration-damping brackets in high-shock environments.
Maintain minimum 15mm clearance from adjacent components for heat dissipation.
Use M5x0.8 mounting screws with 0.6-0.8Nm torque. Perform manual override test
quarterly using integrated override button.
Critical note:
Not compatible with phosphate ester fluids. When using in vacuum applications,
install downstream check valve to prevent backflow contamination.
