The EAV420 features a robust aluminum alloy body with hardened brass cores, optimized for high-frequency switching in industrial automation. Its low-friction spool design ensures ≤0.1 MPa minimum operating pressure differential. Requires 5μm filtered lubricated air (ISO 8573-1 class 4) for optimal performance.
- Automated assembly line clamping/unclamping systems
- Plastic injection molding machine ejectors
- CNC tool changers with dual-position control
- Textile machinery air cylinder sequencing
- Bottle capping station actuators
Installation protocol:
Mount in vibration-controlled environments using M4 mounting screws.
Maintain ≥15mm clearance below manifold surface for heat dissipation.
Perform monthly lubrication checks in continuous operation scenarios.
Critical note:
Avoid rapid pressure fluctuations >0.2 MPa/sec to prevent spool seizure.
Always install downstream pressure regulators for pulsation-sensitive applications.
