Y43H pilot steam pressure reducing valve Feature
Y43H pilot steam pressure reducing valve belongs to pilot piston type pressure reducing valve.The pressure reducing valve is composed of main valve and pilot valve.Main valve is composed of valve seat, valve plate, piston, cylinder sleeve, spring components.The guide valve mainly consists of seat, disc, diaphragm, spring, adjusting spring and other parts.The outlet pressure of Y43H pilot steam pressure reducing valve is set by adjusting the spring ,which is transfer the outlet pressure changes according to the diaphragm sensor, and the piston is driven through the opening and closing of the guide valve to adjust the flow area of the main valve throttling position, so as to realize the pressure reducing and pressure stabilizing function.Y43H pilot steam pressure reducing valve is mainly used for steam pipeline, super decompression and pressure stabilization.
Y43H pilot steam pressure reducing valve is applicable to urban construction, chemical industry, metallurgy, petroleum, pharmaceutical, food, beverage, environmental protection and other industries. -
