The Y43H pilot piston type steam pressure reducing valve consists of two parts: the main valve and the pilot valve. The main valve is mainly composed of valve seat, valve disc, piston, cylinder liner, spring and other parts. The pilot valve is mainly composed of valve seat, disc, diaphragm, spring, adjusting spring and other parts. Y43H piston type steam pressure reducing valve has been greatly improved on the basis of ordinary pressure reducing valve, which enlarges the piston area and changes 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. By adjusting the spring pressure and setting the outlet pressure, the diaphragm is used to sense the change of the outlet pressure, and the piston is driven by the pilot valve to adjust the throttle area of the main valve to realize the function of reducing pressure and stabilizing pressure. Y43H piston type steam pressure reducing valve is mainly used for steam pipeline, which has the function of ultra low pressure and steady pressure.
