Precision exhaust-side flow controller with quarter-turn micrometer adjustment, featuring a dust-resistant cap and color-coded rotation indicator (blue for air exhaust). The anti-vibration lock nut ensures stable settings in high-frequency machinery. Compatible with ISO 1/8 ports and optimized for cylinder speed regulation through exhaust restriction.
- Pneumatic cylinder deceleration control
- Assembly line workpiece damping systems
- Packaging machine gripper positioning
- Medical bed actuator speed regulation
- Textile machinery tension control
Installation note:
Install within 300mm of cylinder exhaust port for optimal response.
Use 2.5mm hex key for flow adjustment. Lubricate with ISO VG32 oil if
using dry air. Avoid overtightening - maximum torque 0.8N·m.
