Hilton Bonneted Knife Gate Valves provide performance, economy and rugged construction for a broad range of water and industrial applications including Water, Wastewater, Paper, Mining, Power and Hydro Dams. A leader in fabricated valve technology, Hilton offers standard Bonneted Knife Gate Valves in sizes 2-96″, and custom fabricated valves to 144″ with higher pressures and temperature capabilities to meet particular application requirements.
Bonneted Knife Gate Valves can be built to U.S. or international standards, and are available with wafer or special extended face-to-face dimensions for replacement of existing valves. Bonnets can be pressurized or un-pressurized, and can be specified with optional flushing or drain ports. A back seat seal ring on all bonneted valves allows valves to be repacked without valve disassembly and with the valve in the pipeline under pressure.
