High-flow directional control valve with triple position memory function, featuring anti-vibration coil design and zero-pressure differential operation capability. The aluminum alloy body with chrome-plated brass spool ensures corrosion resistance in humid environments. Includes manual override and position indicator for system diagnostics.
- Pneumatic cylinder sequencing in automated assembly lines
- Plastic injection molding machine clamp control
- Textile machinery tension regulation systems
- Food processing equipment with frequent direction changes
- Automotive brake testing rigs
- Water treatment plant valve clusters
Installation requirements:
Requires 5μm filtration with auto-drain function. Mount horizontally
with vibration isolators when used in mobile machinery. Lubricate with
ISO VG32 turbine oil if operating below -5℃. Maintain minimum 20mm
clearance around exhaust ports.
Critical note:
Do NOT use silicone-based lubricants. Allow 30-second cool-down
between rapid cycling operations exceeding 5Hz.
