Detailed explanation and specific parameters of 200P pressure reducing valve
It consists of two parts, the main valve and the pilot valve200P pressure reducing valve.ThatThe main valve is composed of valve seat, piston, main valve disc, spring, cylinder liner and other parts.outlet pressure byADJUST ADJUSTMENT SPRING PRESSURE SETTINGusing the specific change of the diaphragm to sense the outlet pressure, the pilot valve is opened and closed to drive the piston to adjust the size of the flow area of the throttling part of the main valve, so as to realize the function of reducing pressure and stabilizing pressure.
