Lubricated Plug Valve The plug gets lubricated by injecting sealant through injection fitting. The lubricant make sure the smooth movement and prevent the corrosion of plug. Usually, the seat of lubricated plug valve is metal, thus they can withstand higher temperature, available in larger size and higher pressure. Non-Lubricated Plug Valve A non-metallic sleeve or liner is installed in the body cavity of the plug valve. This sleeve reduce the fricion beween plug and body. Meanwhile it prevents the corrosion of plug. Due to non-metallice sleeve, the non-lubricated plug valve cannot be used in high temperature condition. Multiway Plug Valve The multiway plug valve is used for diverting flow in transfer lines. The multiway plug valves we often see are 3 way plug valve or 4 way plug valve.

The cryogenic valves are mainly used in low temperature liquid media, like liquefied natural gas and petroleum products. The reasons why we use extended stem for cryogenic valves are as below: 1.To maintain the temperature of stem packing in a proper level, since the very low temperature will influnce the sealing function of stem pakcing. 2.To prevent the heat outside from entering the valve and cause energy loss to the application 3.The long stem structure facilitates the quick replacement of the valve's main part through the valve cover. 4.To prevent the parts (like handwheel) over stem from freezing
