Electric ceramic lined knife gate valve

FREE-Valve’selectric ceramic lined knife gate valves are known as slurry gate valves.Itshave 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 arevery 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.

4) Easy to realize the remote control or the local control with electric signal.
