ITT Engineered Valves
Fabri-Valve HD150-300 Heavy Duty Knife Gate Valve
The Fabri-Valve HD line of Heavy Duty Knife Gate Valves is specifically designed to withstand abrasive, high pressure oil sands slurries. The HD valve features a carbon steel body with ANSI B16.34 wall thickness and ANSI B16.5/B16.47 full face flanges, with a double replaceable seat configuration providing bi-directional shutoff. The dual replaceable seats are hard faced with chrome carbide for long-lasting seat and valve life, and six rows of resilient cored packing with internal live-loading combined with two gate scrapers provide superior sealing.
