New knife gate valve for mid-service mining applications

By Chemical Engineering |

The new Clarkson SU10R polyurethane knife gate valve for mid-service applications eliminates the compromise between light-service and heavy-duty valves with a high-performance, low-maintenance, bi-directional, abrasion-resistant design. The two-piece body construction and field-replaceable snap-in liner design provides more reliable sealing than competing products. An integral seat-face seal eliminates the need for flange gaskets in many conventional flanged installations. This, along with an improved gland, will make the product particularly suitable for users across the mining spectrum, from alumina to coal, copper, gold, silver and uranium. The snap-in urethane liner design means that no special tools are required to replace the liner. The valves will initially be available in sizes ranging from 50 to 600 mm, and operate at 10 bars pressure and up to 80°C. — Emerson, St. Louis, Mo.
