A two-stage air valve actuator for a double-diaphragm pump
A device is provided for controlling the air supply to and exhaust from an air driven pump having two diaphragm chambers (44, 46), each with a liquid pumping section and an air section separated by a diaphragm (40, 42). The device comprises a chamber (52) containing a pilot valve (60) for actuation...

| description | A device is provided for controlling the air supply to and exhaust from an air driven pump having two diaphragm chambers (44, 46), each with a liquid pumping section and an air section separated by a diaphragm (40, 42). The device comprises a chamber (52) containing a pilot valve (60) for actuation in accordance with predetermined positions of the diaphragm (40, 42) and an actuator valve for actuation in accordance with the actuation of the pilot valve (60) to direct pressurised air into a corresponding air section of one of the diaphragm chambers (44, 46). A removable cover (28) for the chamber (52) allows access to the valves. |
