Collapsible ball valves 11c67p (KSH.R.) with nominal diameters from 25 to 200

Ball valves 11C67P refer to pipeline valves for industrial purposes and are designed to shut off the flow of working medium transported in pipelines:
- oil refining and gas industry;
- housing and communal services and heating networks.
Working medium: heating network water, steam (t=150°C permanently, t=160°C short-term), oil products, fuels and lubricants and liquids without abrasive impurities.
- Working pressure: up to 4.0 MPa.
- Operating medium temperature: -40°C to +200°C (for version 02), -60°C to +200°C (for version 03).
- Ambient temperature: -40°C to +80°C (for version 02), -60°C to +80°C (for version 03) according to GOST 15150.
OPERATING ENVIRONMENT: Natural gas, liquefied hydrocarbon gases, non-aggressive gaseous media to which the valve materials are corrosion-resistant.
- Working pressure:
natural gas - 1.2 MPa,
other media - up to 4.0 MPa.
