Introduction
The gas pressure reducing valve is a special device that automatically reduces the working pressure of the pipeline. It can reduce the higher liquid pressure in the pipeline before the valve to the level required by the pipeline after the valve. There are many structural types of pressure reducing valves, which can be divided into film type, spring film type, piston type, lever type and bellows type according to the structure. According to the number of valve seats, it can be single-seat and double-seat. According to the position of the valve disc, it can be divided into positive-acting and reverse-acting. According to the medium, it can be divided into nitrogen pressure reducing valve, hydrogen pressure reducing valve, oxygen pressure reducing valve, etc.
Working Principle
The basic principle of the gas pressure reducing valve is to reduce the water pressure by the local resistance of the flow channel in the valve to the water flow.

Basic performance
Voltage regulation range:
The pressure regulating range refers to the range within which the output pressure P2 of the pressure reducing valve can be adjusted and controlled, within which the specified accuracy is required. The pressure regulating range is mainly related to the stiffness of the pressure regulating spring.
Pressure characteristics:
The pressure characteristic refers to the characteristic that the output pressure fluctuates due to the fluctuation of the input pressure when the flow rate g is a fixed value. The smaller the output pressure fluctuation, the better the performance of the pressure reducing valve. The output pressure must be lower than the input pressure - a fixed value that basically does not change with the input pressure.
Flow characteristics:
The flow characteristic refers to the persistence of the input pressure-timing and the output pressure changing 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 less it fluctuates with the output flow.
Notice!
choose attention
Select the type and pressure regulating accuracy of the gas pressure reducing valve according to the requirements of use, and then select its diameter according to the required maximum output flow. When determining the air source pressure of the valve, it should be greater than the maximum output pressure of 0.1MPa. The pressure reducing valve is generally installed after the water separator and before the lubricator or the setter, and be careful not to reverse its inlet and outlet; the knob should be loosened when the valve is not in use, so as to avoid the diaphragm often being affected by pressure deformation its performance.
precautions
1. For the convenience of operation and maintenance, the valve is generally installed upright on the horizontal pipeline.
2. When installing, pay attention to keeping the direction of the arrow shown on the valve body consistent with the flow direction of the medium in the pipeline.
3. In order to prevent overpressure behind the valve, a pressure reducing valve should be installed at a place not less than 4M away from the valve outlet.
