Precision exhaust-side flow control valve with reverse flow check function, optimized for smooth cylinder speed regulation. Features micro-bubble-tight sealing and corrosion-resistant construction. The dual-scale graduated knob allows 270° rotation with 0.02 L/min resolution. Requires ISO 8573-2 Class 4 compressed air (max 5mg/m³ oil content).
- Pneumatic cylinder exhaust speed control in SMC-type systems
- Packaging line gripper positioning adjustment
- Die-casting machine ejection timing regulation
- Automated assembly station buffer control
- Medical device actuator soft-stop implementation
Adjustment protocol:
Always depressurize system before initial adjustment. Turn clockwise to reduce exhaust flow (slower movement).
Perform final tuning under load with 0.1MPa minimum backpressure. Apply thread sealant on male ports during installation.
