How does diaphragm valves work?

Alfa Laval diaphragm valves have two modes of operation: manual operation using a handle and automatic operation using a pneumatic actuator.

For manual operation, simply turn the handle to lift the compressor upwards. This moves the diaphragm away from the weir of the valve body, thereby opening the valve. Turning the handle in the opposite direction pushes the compressor downwards onto the diaphragm, pressing the diaphragm against the weir of the valve body and closing the valve.

For automatic operation, a pneumatic actuator controls the axial movement of a piston, thereby opening or closing the valve, depending on the actuator function.
