FREE-VALVE's Ceramic Knife Gate Valves are known as slurry gate valves. Its have simple structure and can cut off medium which contains solid particles and fibers, but for some very hard particles or serious erosive mediums, general metal seated knife gate valves will be washed out easily, so ceramic knife gate valves are very suitable for those mediums containing  fibers and hard solid particles.

Features:

1) Short  length of structure,saving material ,lightweight ,easy to install，small space occupation.

2) Seat is designed with single seat type to prevent sticking and accumulation of ash residue.

3) The sealing surface is made of structure ceramic with abrasion resistance and long service life.
