China Non-lubricated Plug Valve Product introduction
China Non-lubricated Plug Valve Manufacturer, Factory and Supplier In China. Non-lubricated Plug Valve is robust in construction and easy to maintain in-line. Non-lubricated Plug Valve is sleeved quarter-turn plug valve that achieve sealing through the use of a compressible sleeve as a sealing member. In many applications, they operate virtually maintenance-free for decades. Non-Lubricated Plug Valve (Sleeved plug valve) is used for on/off and throttling service. Non-Lubricated Plug Valve is used in a variety of industries, including petroleum, the chemical industry, pharmacy, chemical fertilizer, and the electric power industry.
Non-lubricated Plug Valve is bi-directional flow, simple actuation, lightweight, compact design, and multiport configurations, all of which facilitate improved system design. The inert PTFE sleeve completely surrounds the plug. The sleeve provides a large, circumferential sealing surface from port to port. Open, closed, or rotating, the seal is assured. As the plug rotates, the 360° port lips provide a self-cleaning action to remove scaling and adhering media. Non-lubricant valves are used where less maintenance is required. The friction between the plug cone and body is reduced by sleeves. However, non-lubricated plug valves are limited by the temperature and chemical compatibility of their non-metallic materials. Non-lubricating plug valve is used to regulate the process fluid, such as sulfur, hydrogen fluoride, or where liquids could be trapped or solidified and potentially clog the valve.
