Valvesonly is a Non lubricated plug valve manufacturer in USA. A tapered or cone-shaped wedge serves as a wedge and pushes a polymeric sleeve against the body cavity in the Non Lubricated Plug Valve. The sleeve eliminates friction between the plug mechanism and the body. Non lubricated Plug Valves are often used instead of lubricated ones in applications where minimal maintenance is needed, such as special services in sulphur or hydrogen fluoride, or where liquids can become stuck or solidify, potentially jamming the valve. Temperature and the chemical compatibility of the non-metallic materials used to make the non-lubricated plug valves must be held in mind. The flow of the medium is started or stopped using a tapered or cylindrical plug in a non-lubricated sleeved plug valve. The plug inside this sort of valve is not lubricated. These valves come in a wider variety of sizes. They are suitable for use in high-pressure, high-temperature environments. It is also made of anti-corrosive materials, which stops the valve from corroding. By raising the plug, it eliminates friction between the plug face and the body seat during service.
