Ball valves perform a quarter turn on/off or modulating function. A
flow-controlling ball located within the body of the valve contains a hole
through its center along one axis, which connects the inlet and outlet
ports of the body. The ball itself is held in place by, and rotates 90º
within, PTFE seats. These provide permanent lubrication and keep the valve
"bubble-tight." They are backed by elastomeric cushions, which provide
pressure against the ball and at the same time compensate for wear. Elastomer
O-rings are used for stem and carrier seals to prevent leakage to the atmosphere.
In the open position, the flow is straight through with minimal pressure
drop as long as the porting through the ball is the same size as the inside
diameter of the pipe.
