Valve can be operated manually, either by the handle, the lever pedal and others. Besides being able to be operated manually, the valve can also be operated automatically by using the principle of changing the flow of pressure, temperature, etc. These changes can affect the diaphragm, spring or piston which in turn activates the valve automatically.
