Reliable Bi Directional Knife Gate Valve suitable for various industrial process applications
A bi-directional knife gate valve is designed to provide shut-off against pressure from either side of the valve, making it suitable for pipelines where flow direction can change. Bi Directional Knife Gate Valve Suppliers in South Africa can provide these valves for slurry, wastewater, pulp, mining and industrial systems. African Valve supplies bi-directional knife gate valves for applications requiring flexible flow-direction isolation.
