High-flow directional control valve with triple position functionality, featuring a unique pressure-balanced spool design for reduced actuation force. The aluminum alloy body with hard anodized treatment ensures corrosion resistance in humid environments. Integrated surge suppression diodes protect against voltage spikes.
- Industrial robot end-effector tool changers
- Plastic injection molding machine clamp control
- Automated assembly line positioning systems
- Textile machinery tension control units
- Semiconductor wafer handling equipment
Installation note:
Requires minimum 5μm filtration (with auto-drain). Maintain horizontal mounting
with exhaust ports downward. Use shielded cable for coil connections in EMI-sensitive
environments. Allow 15mm clearance around valve for heat dissipation.
Critical notice:
Do NOT use silicone-based lubricants - compatible with ISO VG32 hydraulic oil only.
Center position leakage ≤3 bubbles/min when tested per ISO 6358 standards.
