Structure, Properties and principle: the valve plug and piston ring seal structure of a metal and nonmetal multilayer sealing composition BUJ41H shutoff valve vendors, when a piston ring that is worn in a long time using the operation has been regulating the regulator to zero When the shut-off valve has failed BUJ41H prices, so the second track off metal cone piston seal plays simultaneously, so long as the ordinary life of the valve piston valve several times, so no special maintenance during use and remain leak , to achieve a leak-free piping select BUJ41H better shutoff valve opening and closing device manufacturer, to save energy and reduce environmental pollution and labor has obvious applications. Features: piston ring according to the different choice of material for the media to fully enhance the scope of its use, high temperature, wear, corrosion, strong rebound performance, after prolonged use, maintenance adjustable piston ring if worn increased pressure original state. Repair and replacement piston ring process is simple and convenient, without removing the valve body from the pipeline after the steam stop valve cover assembly can be replaced to remove the new piston ring repetitive use features.
