Gate valve Elephant GVKRxxx-2W-Fb-OST DN50-150 16 bar stainless steel, interflange with OST flange and bare stem for electric drive, designed for installation on pipelines as a shut-off device and for regulating the flow of working media in water supply systems (except for drinking water supply systems) and in the chemical industry.
The principle of operation of a gate valve is to move the gate (knife) perpendicular to the flow of the medium. When the nominal diameter of the pipeline is completely blocked, the flow stops; when partially blocked, the flow is regulated.
