    Tips: When is it necessary to replace the sealing parts on the knife gate valve?

    Many processors today use knife gate valves in larger sizes to handle the thicker flows of light grease, heavy oil, varnish, slurry, waste water and paper pulp with greater ease. It is important to note that these valves do have low pressure restrictions and are designed to hold the blade in the elastomer seal after it has cut through the substance it is handling. Viscous liquids can easily slide through these soft seals without disturbance, however, when solids or powders pass through the knife gate, large, dry material will eventually build up into the soft seal located at the end of the gate. When this happens, the seals will eventually fail to close tightly. If this happens, the seal will need to be replaced.
