Precision-engineered throttle valve featuring micro-flow adjustment capability through a knurled knob with 300° rotation range. The dual-seal structure prevents leakage during high-frequency adjustments. Optimized for stable flow control in low-pressure pneumatic systems, with anti-corrosion treatment for humid environments.
- Pneumatic cylinder speed regulation in assembly lines
- Air blow system flow control for CNC machines
- Vacuum generator adjustment in packaging systems
- Medical device pneumatic timing controls
- Laboratory instrument air pressure stabilization
Installation note:
For optimal performance, install downstream of filter regulator.
Complete 3 full clockwise turns before initial adjustment to prevent seal damage.
Use PTFE tape on male threads only, avoiding entry into airflow path.
- Clean monthly with compressed air (≤0.3MPa)
- Lubricate adjustment thread with silicone grease (JIS K2220) every 6 months
- Replace O-rings after 500,000 adjustment cycles
