The wedge gate valve is designed for installation as a shut-off device on pipelines for transportation of water, steam, oils, in relation to which the materials used in the gate valve are corrosion-resistant.
The multi-turn actuator is designed for automation of industrial valve control process and for determining the position of the valve shut-off body.
