Urethane Lines Knife Gate Valve (KUL)


Technical Information

DeZURIK’s KUL Urethane Lined Knife Gate Valves are designed for on-off and throttling applications of abrasive slurry and dry abrasive materials. Urethane Lined Knife Gate Valves are 100% port area and are ideally suited for applications in mining, chemical and food industries.


Urethane Lined Knife Gate Valves are available in sizes 2-48" (50-1200mm) with temperature ratings from -40 to 180°F (-40 to 82°C) as standard, with a variety of urethane compounds available on application.


KUL valves feature a one-piece, cast-in-place liner that provides bi-directional, drip-tight shutoff to either 150 or 250 psi (1030 or 1720 kPa) CWP. All wetted surfaces of the ductile iron body are lined with urethane. KUL is good for dead-end service.
