- Pneumatic counterbalance systems
- Medical device pneumatic braking controls
- Packaging machine clamp speed modulation
- 3D printer pneumatic extruder controls
- Laboratory automation timing mechanisms
Installation protocol:
Always install on exhaust port of cylinder. For optimal performance:
1. Mount vertically with adjustment knob upward
2. Use 40μm filter upstream
3. Apply thread sealant on male threads (PTFE tape prohibited)
4. Perform flow calibration under actual operating pressure
