LD Strizh ball valve of steel 20 DU50 RU16MPa P/P

Cranes are used for transportation of drinking, technical water, natural gas and other media,
in relation to which the materials of the valve are corrosion-resistant. The product is used for complete shut-off of the flow of the transported medium.
The valves are designed for use in existing systems as a replacement for gate valves (30C41NZh, 30Ch6BR) and butterfly valves,
as well as in the design and construction of new engineering networks.
The valve design provides rigidity and tightness class "A" in the temperature range from -40°? to +200°? (version 02), from -60°? to +200°? (version 01, 03).
Ball valves are fully ready for use, do not require maintenance during the whole service life.
throughout the entire service life. Spatial position of the valve on the pipeline - any.
For preventive purposes, as well as to prevent the formation of deposits on the surface of the ball (jamming)
it is necessary to check the mobility of the travelling parts by turning the handle by 10-15 degrees 2 times a year.
