The gas pressure reducing valve is mainly used in water, steam, and air medium pipelines. It has the advantages of simple structure, stable pressure, light weight, convenient adjustment and installation. Today we come to understand the three basic performance of gas pressure reducing valve.

1. Pressure regulation range

The pressure regulation range refers to the adjustable range of the output pressure P2 of the combustion pressure reducing valve, within which the specified accuracy is required. The pressure regulating range of the gas pressure reducing valve is mainly related to the stiffness of the pressure regulating spring.

2. Pressure characteristics

Pressure characteristics refer to the characteristics of output pressure fluctuations caused by input pressure fluctuations when the flow g is a constant value. The smaller the output pressure fluctuation, the better the characteristics of the gas pressure reducing valve. The output pressure must be lower than the input pressure-the fixed value does not basically change with the input pressure.

3. Flow characteristics of gas pressure reducing valve

The flow characteristic refers to the input pressure-timing, the output pressure changes with the change of the output flow g. When the flow rate g changes, the smaller the change in output pressure, the better. Generally, the lower the output pressure, the smaller the fluctuation of the output flow.

According to statistics, 80% of gas accidents are caused by the quality of gas pressure reducing valves and improper use by users. Therefore, we must use gas pressure reducing valves correctly to improve safety awareness and prevent gas accidents.
