Selection of High Pressure Gas Pressure Reducing Valve: The type and pressure regulating accuracy of the high-pressure gas pressure reducing valve are selected according to the usage requirements, and its diameter is chosen based on the required maximum output flow rate

Product Details

Selection of High Pressure Gas Pressure Reducing Valve:
Select the type and pressure regulation accuracy of the high-pressure gas pressure reducing valve according to the usage requirements, and then choose its diameter based on the required maximum output flow rate. When determining the gas source pressure of the valve, it should be greater than the maximum output pressure by 0.1MPa. The pressure reducing valve is generally installed after the water separator and before the oil mist or setting device, and care should be taken not to connect its inlet and outlet in reverse; When the valve is not in use, the knob should be loosened to avoid frequent deformation of the diaphragm under pressure, which may affect its performance.
The installation and maintenance of high-pressure gas pressure reducing valves should pay attention to the following matters：
1. For the convenience of operation and maintenance, this valve is generally installed upright on a horizontal pipeline.
2. During installation, attention should be paid to ensuring that the flow direction of the medium in the pipeline is consistent with the direction of the arrow shown on the valve.
3. To prevent overpressure behind the valve, a pressure reducing valve should be installed at a distance of no less than 4M from the valve outlet.

Application scope of high-pressure gas pressure reducing valve
High pressure gas pressure reducing valves are suitable for gas pipelines such as air, liquefied gas, oxygen, etc. with a working temperature of ≤ 70 ℃. This valve reduces the inlet pressure to a certain required outlet pressure through throttling of the opening and closing components, and uses the energy of the medium itself to automatically meet the predetermined requirements and adapt to the working conditions.Pressure rating: PN1.0MPa-32.0MPa
