Ball valves use a handle to turn a ball in the valve, with a hole or
port through it. The ball is used to allow or prevent flow through the valve depending on its position. If the hole is
aligned with the pipe, flow continues through the valve; if the hole is perpendicular to the pipe, flow will stop at the
valve. It’s really that simple! Visualizzare
