High-flow 5/2-way valve optimized for bidirectional cylinder control in industrial automation. Features zero-pressure start capability and surge protection circuitry. The low-hum design reduces coil temperature by 18% compared to standard models. Requires 5μm filtered lubricated air (ISO 8573-1 class 4-4-3).
- Pneumatic press brake directional control
- Robotic arm gripper sequencing
- Plastic injection molding machine ejectors
- Automotive assembly line clamping systems
- CNC tool changer mechanisms
Installation guidelines:
Maintain ≤3° deviation from vertical mounting position. Use copper-free
anti-vibration brackets in high-cycle applications (>5Hz). Lubricate
spool monthly with ISO VG32 pneumatic oil if using non-lubricated air.
