Proportional pressure reducing valve: a pressure reducing valve with a stable proportional relationship between inlet pressure and outlet pressure; ② Adjustable pressure reducing valve: a pressure reducing valve with adjustable outlet pressure; ③ Stable pressure reducing valve: a pressure reducing valve in which the outlet pressure remains relatively stable and does not change with changes in inlet pressure and flow rate; ④ Differential pressure reducing valve: a pressure reducing valve with a relatively stable dynamic pressure difference between the inlet and outlet; ⑤ Direct acting pressure reducing valve: a pressure reducing valve that uses the differential force between the spring and the diaphragm to directly drive the valve plate to open and close, achieving pressure reduction; ⑥ Pilot pressure reducing valve: a pressure reducing valve that utilizes hydraulic control of the main valve opening and closing through a pilot valve (direct acting pressure reducing valve) to achieve pressure reduction; ⑦ Double stage pressure reducing valve: a pressure reducing valve composed of a two-stage series pressure reducing device, also known as a series pressure reducing valve.
