The wedge gate valve is designed for installation as a shut-off device on pipelines for transporting water, steam, oils, in relation to which the materials used in the gate valve are corrosion-resistant.
The multi-turn electric drive is designed to automate the process of controlling industrial valves, as well as to determine the position of the valve shut-off element.
