Claim:
A knife-style gate valve for use on wet scrubbers to control liquid slurry flow, said knife-style gate valve comprising: a near body assembly; a distal body assembly connected to said near body assembly; a bonnet located atop said near and distal body assemblies; a hand wheel connected to said bonnet; a gate valve assembly intercalated between said distal and near body assemblies, comprising: a near body liner; a distal body liner; a wiper positioned above said near and distal body liners; and, a gate passing through said wiper; a stem connected to said bonnet; and, a link pin connecting said stem to said gate valve assembly; wherein each of said near and distal body assemblies further comprises: a yoke located above said gate valve assembly and attached to said bonnet; a plurality of viewing holes formed in said yoke for identifying an open or a closed state of said gate valve assembly; and, a plurality of connection apertures located at flanged portions of said near body assembly and said distal body assembly respectively; wherein said hand wheel actuates said gate between said distal and near body assemblies respectively; wherein rotation of said hand wheel causes said gate to linearly reciprocate through said wiper; wherein said wiper allows said gate to operate in between said near body liner and said distal body liner; wherein said gate is visible through an upper set of said viewing holes when said gate is at said open state; wherein said gate is visible through a lower set of said viewing holes when said gate is at said closed state; and, wherein said near body liner and said distal body liner pass through an entire cross-section of said near body assembly and said distal body assembly, respectively.
