Commonly knife edge gate valves are uni-directional valves, but for some special applications, bi-directional valves are used to regulate the flow. We have designed a range of bi-directional knife edge gate valves for such special applications. It efficiently performs with minimum pressure drop. Design of the valve helps to provide maximum flow area to allow uninterrupted flow of the medium. This special design of valve has U-shaped elastomer seal to provide perfect seal. Our novel adopted technology is the authentication to suggest best possible solution for special purpose. Our valves are constructed with high grade material that serves the purpose of lower operating cost. It is highly preferred for the model process management for variety of flow medium.
