YGa43H high sensitivity and large flow steam pressure reducing valve consists of two parts: main valve and pilot valve. The main valve is mainly composed of valve seat, main valve disc, piston, spring and other parts. The pilot valve is mainly composed of valve seat, disc, diaphragm, spring, adjusting spring and other parts. This product has been greatly improved on the basis of ordinary pressure reducing valve, increased the piston area and changed the throttle structure. Change the seal form, increase the flow area and so on, thus greatly improving the sensitivity, flow rate, life and other aspects of performance.


YGa43H high sensitivity large flow steam pressure relief valve is mainly used for steam pipeline, suitable for large flow and large change in inlet pressure steam pipeline.
