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.

Both y strainer and basket strainer take their name from their configurations. There are four differences between them. -First, y strainer can be installed either horizontally or vertically. But in most cases, basket strainer could only be in horizonal position. -Second, y strainer could handle higher pressure rating than basket type. -Third, for the ability to screen particulate, basket strainers are better than y strainers. -Lastly, basket strainer is easier to be cleaned than the y type strainer. In conlusion, Y-strainers are applicable for high-pressure pipelines with a low concentration of particles & solids and less cleaning needs. Vice versa for basket type strainer.
