How It Works: Ball Valves | SLB
When the valve is closed, the core is wedged against the seat, ensuring positive shutoff. When the valve is open, the core tilts away from the seal, and flow passes uniformly around the core face. ORBIT rising stem ball valves leverage this operating principle, delivering fast, low-torque operation and long-term, reliable performance.

Grid-tied electrical system
A grid-tied electrical system, also called tied to grid or grid tie system, is a semi-autonomous electrical generation or grid energy storage system which links to the mains to feed excess capacity back to the local mains electrical grid. When insufficient electricity is available, electricity drawn from the mains grid can make up the shortfall.
