pressure
reducing valve can automatically reduce the high-pressure input to a stable
low-pressure output, and is not affected by the flow rate or input pressure
changes. The output pressure is maintained within a preset range
through a precise pressure regulating pilot. When the output pressure
exceeds the set range of the pressure reducing valve, the pressure reducing
pilot and the main valve will automatically close to form a tight seal.
If the optional check
feature is selected, when the reverse pressure is generated, the backflow fluid
will enter the upper chamber, closing the valve and preventing the flow back
