The Amanzi SA ball valve
The Amanzi SA ball valveis a manually operated, quarter-turn valve used for isolating (ON/OFF) – not for regulating. The valve has a flow-controlling spherical ball located within the valve body. A hole through the centre of the ball connects the inlet and outlet ports of the body. By turning the handle, the ball inside is turned 90°, which blocks the opening and stops water flowing through. The Amanzi SA ball valve is a full-bore valve with no pressure drop, allowing free flow when in the open position, as the ball opening is the same size as the inlet/outlet.
