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. In case of complete closing of the pipeline nominal bore diameter the flow is stopped, in case of partial closing the flow is regulated.
