A diaphragm control ball valve has double statuses, a ball valve and a diaphragm control valve. They are named from different perspectives.
A diaphragm check valve uses a flexing rubber diaphragm positioned to create a normally-closed valve. Pressure on the upstream side must be greater than the pressure on the downstream side by a certain amount, known as the pressure differential, for the check valve to open allowing flow. Once positive pressure stops, the diaphragm automatically flexes back to its original closed position. While a ball valve is a valve with a spherical disc, which is the control part. The sphere has a hole through the middle so that when the port is in line with both ends of the valve, flow will occur. When the valve is closed, the hole is perpendicular to the ends of the valve, so that flow is blocked.
