Bonneted metal-seated knife gate valves from Lined Valve Company have the ability of instant shut-off in solid materials without clogging. The design of a bonneted knife gate valve specifically addresses fugitive emissions and packing leakage, as its round stem is easier to seal, and the packing area is greatly reduced, producing a better seal. They are manufactured with a stainless steel body, gland and yoke, and stainless steel gate and stem for durability and corrosion resistance. They are certified to MSS SP-81 and AWWA C520. 888/256-5779; www.linedvci.com.
