The Electric Hydraulic Bi-directional Knife Gate Valve is a heavy-duty automation solution for high-cycle slurry and wastewater service. It utilizes an integrated electro-hydraulic actuator to provide massive thrust for cutting through thick media while maintaining a bubble-tight seal in both flow directions. The bi-directional design prevents seat displacement under backpressure, making it ideal for complex piping networks, mining tailings, and pump stations requiring remote, high-torque operation.
