Description
The gate valve is designed for installation on the pipeline as a shut-off device and regulation of the working medium flow in water supply systems (except for drinking water supply systems) and chemical industry. The principle of operation of the gate valve is to move the gate (knife) perpendicular to the flow of medium. At full closing of the pipeline nominal bore diameter the flow is stopped, at partial closing the flow is regulated.
The multi-turn actuator is designed to automate the process of control of industrial valves, as well as to determine the position of the valve shut-off body.
