The untreated production stream from hydrocarbon wells contains sand, scale, water and often, corrosive compounds like hydrogen sulphide and carbon dioxide.
These, together with the mixture of oil and gas flowing under high pressures, exert severe wear on the seat to ball interfaces of the downstream valves.
The Eccentric-Ball Valve is a Patented single valve that provides excellent performance in these erosive conditions and provides full double block and bleed functionality in a single valve.
