The self-operated pressure regulating device is a valve assembly that utilizes a pressure regulating valve and a bypass stop valve to adjust the pressure to the desired level. It is designed with inlet and outlet flanges, stop valves, pressure regulating valves, safety valves, pressure gauges, filters, vent valves, etc. The model of the pressure regulating valve and the diameter of the pipeline in the pressure regulating device are determined based on the required adjusted pressure and flow rate, and it is suitable for pressure regulation of gases such as oxygen, argon, nitrogen, carbon dioxide, natural gas, etc.
