- Air tool exhaust flow control
- Packaging machine actuator synchronization
- Medical equipment pneumatic braking systems
- Semiconductor handling robot end-effectors
Installation note:
Install vertically with flow arrow aligned to direction control. For optimal performance,
maintain 50mm clearance from heat sources and use upstream filtration (≤40μm).
Lubricated air (ISO VG32) recommended for extended seal life.
