Ball valve information

Goole Ball valves are used to turn liquid and gas flows fully on and off with only a quarter turn of a ported ball within the valve from a handle or powered actuator. Ball valves are found in every shutoff valve application, with plastic versions of one inch size and less being available for domestic service for a few dollars all the way to industrial models several feet in diameter made from exotic metals costing tens of thousands of dollars.

Goole Valve Construction
Ball valves consist of a smooth shiny metallic or plastic ball locked in a smooth cavity with a ring shaped seal on either side of the ball concentric with the entry and exit ports of the valve. The ball has open bore or port through the middle of the ball in only one direction. A handle is connected through the side of the valve to the ball with a sealed valve stem shaft. When the valve is off, the port is perpendicular to the pipeline containing the valve, and flow is completely blocked.

Operation
Valve operation is intuitive--when the handle is perpendicular to the direction of the pipe, flow is shut off. When the handle is turned to be parallel to the pipeline, the ball also turns 90 degrees and the port opens one end of the valve to the other and flow is virtually unrestricted from one side of the valve to the other.
