Y43H ~ Y43Y high sensitivity steam valve consists of two parts of the main valve and pilot valve. The main valve from the valve seat, the main valve disc, piston, cylinder liner, springs and other components. Pilot valve mainly by the valve seat, disc, diaphragm, spring, adjusting spring and other components. By adjusting the spring pressure set outlet pressure, the use of diaphragm sensing outlet pressure changes, through pilot valve opening and closing drive piston to adjust the size of the main valve throttle flow area size, to achieve decompression regulator function. The piston area is enlarged, the throttle structure is changed, the sealing form is changed, the pilot valve structure is improved and the spring shape is adjusted, thereby improving the performance of the product from the following aspects. Improve the sensing performance of the outlet pressure change, improve the sensitivity, and greatly reduce the pressure deviation caused by factors such as the upstream pressure change and the flow rate change. Improved streamline distribution and reduced noise. Improved sealing surface structure, extending the sealing surface life. This product is mainly used for steam pipe, suitable for large changes in inlet pressure, steam flow changes in large pipelines.
