Cast steel sleeved plug valve introduction:
Cast steel sleeved plug valve is the use of a plug with a through hole as the opening and closing parts,Cast steel sleeved plug valve body rotation with the stem to achieve the opening and closing action of the plug valve. Cast steel sleeved plug valve body is mostly cone, also has the cylinder body. Teflon sleeve type plug valve is simple structure, quick opening and closing, small flow resistance, convenient maintenance, good sealing performance, etc.Cast steel sleeved plug valve is sealed through the sealing surface around the sleeve.Unique 360° metal lip protection fixed sleeve, Cast steel sleeved plug valve has no cavity for medium accumulation, metal lip provides self-cleaning function when the sleeve plug valve turns,Teflon sleeve type plug valve is suitable for sticky and easy to scale working condition, two-way flow, more convenient to use and install.Cast steel sleeved 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.

Cast steel sleeved plug valve working principle 
Cast steel sleeved 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 Cast steel sleeved 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 a 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.
