High sensitivity large flow steam reducing valve-Pressure reducing valve series-减压阀厂家-上海冠环阀门制造有限公司

Product overview

The high sensitivity and large flow steam reducing valve is composed of a main valve and a pilot valve. The main valve is mainly composed of seat, main valve disc, piston, spring and other parts. Pilot valve is mainly composed of seat, disc, diaphragm, spring, adjusting spring and other parts. The steam reducing valve has been greatly improved on the basis of the ordinary reducing valve, increasing the piston area and changing the throttling structure. The sealing form is changed, the flow area is increased, etc., so that the performance is greatly improved in terms of improving sensitivity, flow rate and life. It is suitable for steam pipelines with large flow rate and large flow rate change and large inlet pressure change.
