Sleeved Plug Valve

Sleeved Plug Valve

Ball valves have been widely used in low temperature and cryogenic applications, including LNG (Liquefied Natural Gas) which is now a better choice of energy. Find trusted cryogenic trunnion mounted ball valves and floating ball valves here.

Introduction of Sleeved Plug Valve

The sleeved plug valve is composed of valve body, valve cover, sleeve, plug and other parts. The plug hole is aligned or staggered with the valve body hole by rotating the plug with hole. The valve is suitable for food, petroleum, chemical, pharmaceutical, chemical fertilizer, electric power, precious metal pipeline with nominal pressure class 150lb-900lb and working temperature – 29-180 ℃.

Cryogenic Valves Industrial Applications

  • Sleeved plug valve has the advantages of exquisite structure, reliable sealing, long sealing life, superior performance and shape in line with the process aesthetics.
  • Through the soft sleeve and metal plug interference fit to ensure the sealing, adjustable strong.
  • Sleeve plug valve can be installed in all directions, and is not controlled by the installation direction; The valve is small in volume and has no special requirements for installation space.
  • Sleeved plug valve can be used for two-way flow, easy to be made into a multi-way form, and it is convenient to control the flow direction of pipeline medium.
  • Unique 360 between the sleeve and the valve body ° Metal lip can effectively protect and fix the sleeve, make it not rotate with the plug, and can seal the contact surface of the sleeve and valve body more reliably and stably.
  • When the plug is turned, the sealing surface will be scraped and applied to provide self-cleaning function, which is suitable for viscous and easy scaling medium.
  • Sleeved plug valve does not have internal cavities to accumulate media.
  • The valve is easy to be made into a fire and anti-static structure.
