Y43H leadPiston type steam pressure reducing valveIt 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, valve disc, diaphragm, spring, regulating spring and other parts. The Y43H piston type steam pressure reducing valve has made significant improvements on the basis of ordinary pressure reducing valves, increasing the piston area and changing the throttling structure. By changing the sealing form and increasing the overcurrent area, the performance has been greatly improved in terms of sensitivity, flow rate, and other aspects. By adjusting the spring pressure and setting the outlet pressure, the diaphragm is used to sense the change in outlet pressure. The opening and closing of the pilot valve drives the piston to adjust the size of the overcurrent area at the throttle position of the main valve, achieving the function of pressure reduction and stabilization. Y43H piston type steam pressure reducing valve is mainly used in steam pipelines for super pressure reduction and stabilization.
