Electro hydraulic blind valve
The Electro Hydraulic Blind Valve is an advanced automated pipeline isolation valve designed for safe, efficient, and reliable positive isolation in industrial piping systems. Combining electric control technology with hydraulic drive power, the valve provides high operating torque, precise control, and stable performance for large-diameter and high-pressure pipeline applications.
Also known as an electro-hydraulic spectacle blind valve or electro-hydraulic line blind valve, it is designed to replace traditional manual blind plate operations, enabling remote control, automatic switching, and safer maintenance procedures.
The valve adopts a sector blind plate structure, providing clear open/close status indication and ensuring complete pipeline isolation during maintenance, inspection, and emergency shutdown operations. It is widely used in oil & gas, petrochemical, chemical, power generation, metallurgy, and large-scale industrial pipeline systems.
