1. Accurately adjusting the oxygen flow rate greatly improves the accuracy and efficiency of experiments and production.

2. Provide real-time flow readings, making it more convenient for operators to adjust the oxygen flow rate.

3. Can ensure the stability of oxygen flow rate, reduce production costs, and improve product quality.

Adjust high-pressure oxygen to a suitable low-pressure oxygen for use, ensuring a stable supply of oxygen for people's health and work safety. In the medical field, oxygen pressure regulating valves are indispensable equipment in respiratory therapy.
