FREE-VALVE’sPneumaticCeramic lined Knife Gate Valves are known as slurry gate valves. Its have simple structure and can cut off medium which contains solid particles and fibers,suitable for some very hard particles or serious erosive mediums.They are installed to replacegeneral metal seated knife gate valves which will be washed out easily,
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.
4)Pneumatic operated can save the manpower cost .
