Electro hydraulic knife gate valve
The Electro-Hydraulic Knife Gate Valve is engineered for slurry, pulp, wastewater, and abrasive media systems. Its sharp knife-edge gate effectively cuts through solids, while electro-hydraulic actuation enables precise, automated operation. The valve provides excellent sealing, low maintenance, and long operational life, ideal for mining, power generation, chemical, and bulk material handling industries.
Electro hydraulic knife gate valve
The Electro-Hydraulic Knife Gate Valve combines a robust knife-edge gate with integrated electro-hydraulic actuation for automated control in demanding industrial environments. Its design allows reliable isolation of slurry, powder, pulp, wastewater, and abrasive media, minimizing leakage and wear.
The valve supports full-port flow, reducing pressure drop, and is compatible with remote control, PLC, and DCS systems. High-strength body materials and wear-resistant gate surfaces ensure long-term durability under severe conditions. OEM customization allows adaptation to project-specific sizes, materials, and actuator configurations.
