LUG KNIFE GATE VALVE

Lug Knife Gate Valve Product Information

Lug knife gate valve is also called  slurry valve or mud valve. Its on-off part is the knife type gate, which can cut off fiber materials mediums or similar. Compared with general gate valve, lug type knife gate valve can save much more installation space. lug type knife gate valve is available with metal seated and rubber seated according to different applications. lug knife gate valve is applicable widely in mining, coal washery, steel work, pulp & paper plant, thermal power plant and sewage with fibers treatment. We can manufacture the lug knife gate valve according to standard of MSS SP-81 with sizes of 2″~16″ (DN50~400mm).
