I. Usage
Pressure reducing valves are mainly used to control the pressure of fluids (such as gases and liquids). It is widely used in many industrial and civil fields, such as in gas delivery system to ensure that the gas pressure is stabilized within a safe range; in water supply system to regulate the water pressure to adapt to different needs of use.
II.Second, the working principle
By adjusting the opening of the valve, the fluid generates pressure loss when passing through the pressure reducing valve, thus reducing the downstream fluid pressure. When the upstream pressure rises, the pressure reducing valve will automatically adjust the opening to keep the downstream pressure relatively stable.
III. Features
Precise pressure control, high reliability, multiple types
