steel gate valve is advantageous in applications involving slurries, as their “gates” can cut right through the slurry.
steel gate valve is also used in applications that involve viscous liquids such as heavy oils, light grease.
gate valve can also be used where throttling capabilities are desired, although this is not generally recommended as erosion of the seat and disc occurs due to the vibrations of the disk in throttling applications.the website:
