Product Features: piston ring according to different selection of materials suitable for medium to fully enhance the scope of its use shut-off valves, high temperature, wear, corrosion, strong rebound performance Shandong valve, after prolonged use, if worn piston rings can increase its original state regulator maintenance. Repair and replacement piston ring technology process is simple and convenient cut-off valve plunger insulation prices, without having to detach the body after stopping the steam pipes to remove the valve cover assembly can be replaced with new piston rings repetitive use features. Structural performance and principle: the valve plug and piston ring seal structure has a multi-layer metal and non-metal sealing composition, when a piston ring worn by the regulator to have been in operation for a long time to use the zero voltage regulator has failed BUJ41H- 25 cutoff valve suppliers, so the second track off metal conical piston seal plays simultaneously, therefore the piston valve life of up to several times normal valve, so in the course without special care and maintain not leak, can achieve a better choice pipeline leak opening and closing device for saving energy and reducing environmental pollution labor has obvious applications. BUJ41H-25 cut-off valve, Everbright valve, globe valve, Ltd. provided by Shandong Everbright valve. Valve Co., Ltd. Shandong China Everbright (www.sdgdfm.com) Shandong Weifang, ball leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Everbright valve leadership with the staff warmly welcome all inquiries negotiations to create a better future for China Everbright valve.
