The Through Conduit Knife Gate Valve features a unique "O-port" gate design where a circular opening is machined into the sliding plate. Unlike standard gates, the plate is always in contact with the seats, protecting them from the media flow. When open, the conduit provides a smooth, unobstructed bore, making it the premier choice for high-concentration slurries, recycled paper pulp, and heavy mining fluids where clogging or seat erosion must be avoided.
