A valve operator is mounted on the valve body for moving said diaphragm between the open and closed positions. The main valve body has a side wall and a side wall opening therein in communication with the flow chamber. The side wall has a side wall valve seat formed therein surrounding the side wall opening. A satellite body is mounted on the main valve body and has a satellite flow chamber therein in communication with the side wall opening and the flow chamber in the main valve body. A diaphragm is disposed in the satellite valve body and is movable between open and closed positions with respect to the side wall valve seat. A valve operator is carried by the satellite valve body for moving the diaphragm in the satellite flow chamber between open and closed positions with respect to the side wall seat.
