Description
The gate valve is designed to be installed on the pipeline as a shut-off device and regulate the flow of medium in water supply systems (except 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 bore diameter the flow is stopped, in case of partial closing the flow is regulated.
