Shut-off and regulating valve (type KZR, model range up to DN100 up to PN70,0 MPa; DN150-300 up to PN16,0 MPa)

The shut-off and regulating valve is designed for regulation and shut-off of the working medium flow in technological processes of extraction, processing, transportation and storage of natural gas, oil, liquid and gaseous oil products, water-gas-oil mixtures, oil associated gas, as well as other media, in relation to which the materials of valve parts are corrosion-resistant. The valves are designed for operation in cold macroclimatic region. Scheduled inspection is usually combined with overhaul maintenance. Inter-repair service and scheduled technical inspections are carried out in the terms established by the schedule depending on the mode of operation of the system (unit), but at least twice a year.
