Knife Gate Valve for Mining
What LibertyCES's vendor documentation shows
First knife gate valve captured from any vendor in this project — a distinct architecture from every ball, butterfly, diaphragm, plug and check design in the corpus. The mechanisms are the content: the seat is mechanically locked into the body via a stainless steel retainer ring, and the gates are polished/lapped on both sides with a machined bevel on the bottom edge specifically to cut through solids and seal tighter closed. Meets MSS-SP-81 and TAPPI TIS 405-8. Real discrepancy preserved: AVCO's marketing text references cast iron while its materials list names only 304SS/316SS/Hastelloy — AVCO's own inconsistency, to be resolved with the vendor before quoting cast iron.
