Gate valves are manufactured in accordance with Technical Specification 3741-003-79315310-2007.
Gate valves are used for leak-free cutting off water or steam. These valves are used only for cutting off (opening) pipelines. Connection to pipeline – by welding. Gate valves are operated by means of handwheel, parallel shaft reducer or right-angle reducer, electric drive.
