Non-lubricated sleeve plug valve introduction:
Non-lubricated sleeve plug valve is sealed through the sealing surface around the sleeve.Unique 360° metal lip protection fixed sleeve, Non-lubricated sleeve plug valve has no cavity for medium accumulation, metal lip provides self-cleaning function when the Non-lubricated sleeve plug valve turns,Non-lubricated sleeve plug valve is suitable for sticky and easy to scale working condition, two-way flow, more convenient to use and install.Non-lubricated sleeve plug valve is suitable for cutting off or connecting pipeline medium under nominal pressure CLASS150~CLASS600 and working temperature -29℃ ~ 180℃ in petroleum, chemical industry, pharmaceutical industry, chemical fertilizer industry, electric power industry and other working conditions.Non-lubricated sleeve plug valve is the use of a plug with a through hole as the opening and closing parts, plug body rotation with the stem to achieve the opening and closing action of the valve.The plug body is mostly cone, also has the cylinder body. Non-lubricated sleeve plug valve is simple structure, quick opening and closing, small flow resistance, convenient maintenance, good sealing performance, etc.

Non-lubricated sleeve plug valve working principle 
Non-lubricated sleeve plug valve is with hole plug body as open-close part, through the rotation of the plug body and stem realize on-off movement.ball valve, a rapid switch pass valve, due to the movement between rotating seal face with wiping, and Non-lubricated sleeve plug valve can completely in the fully open to prevent contact with the liquid medium, so it usually can be used in medium with suspended particles.Another important feature is that it is easy to adapt to a multi-channel structure, so that Non-lubricated sleeve plug valve can have two, three, or even four different flow channels.This simplifies the design of the piping system and reduces the number of valves and connections required in the equipment.
