Fabri-Valve OM150 Urethane Lined Knife Gate Valve

Knife gate valve for abrasive and corrosive service, with each body half lined in ITT's proprietary urethane, moulded and bonded to the body and machined to lock in place. A patented one-piece perimeter and chest seal gives bi-directional, bubble-tight shutoff and discharges no process media to the environment. Sized 2" to 24" (DN 50 to 600) and rated 10.3 bar (150 psi) CWP.

Features

Hard urethane lining protects the body from abrasive and/or corrosive media; lining mechanically bonded to the valve body and fully supported to prevent deflection; lining protects the seat from abrasion by direct process flow impingement; moulded triple scrapers clean the gate during operation to protect the integral chest seal; patented one-piece perimeter and chest seal for bi-directional, repeatable shutoff; zero discharge, zero leakage; shouldered perimeter seal locks into the seal groove; excellent bi-directional shut-off even at very low differential pressure; chest seal wraps around the entire gate, eliminating leakage paths; chest seal completely encloses the injectable packing, so loose packing cannot contaminate the process fluid; injectable packing can be adjusted under line pressure without disassembly or removal from the pipeline; robust gate resists distortion from water hammer; tapered liner bore for automatic clean-out and flushing; minimised chest area and close tolerances prevent media packing; raised lining face seals against the pipe flange, so no flange gaskets are necessary; unrestricted straight-through flow for a true full-port design; non-rising stem minimises installation space; universal yoke converts between handwheel and cylinder operation; dished handwheel keeps hands away from pinch points
