High-strength steel knife gate valve
A unique 48-in. knife gate valve, part of the Big Knife family, is made of high-strength 2205 duplex steel for processing more corrosive and abrasive materials. This ferritic/austenitic stainless steel reportedly makes it 50% stronger than austenitic stainless steel valves and more corrosion-resistant in many applications. Its 6-in. (150-mm) face-to-face dimension and assembly without welding offer processing durability and longer life. This virtually eliminates any preferential corrosion due to influence of welding on the crystallographic structure.
Although wider in design and shorter in length than most other valves, the valve has better throughput a
