A valve assembly comprising a main valve body having an inlet flow passage and at least one outlet flow passage and a flow chamber extending between the same. The main valve body has a valve seat surrounding the inlet flow passage. The valve body having an opening in alignment with the inlet in the inlet flow passage. The valve body has an annular shoulder surrounding the opening. A diaphragm is disposed within the flow chamber and sealingly engages the shoulder and movable between open and closed positions with respect to the valve seat. 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.

Main valve construction having a chamber wall with a satellite valve

In an aseptic valve construction, a valve body having an inlet flow passage and at least one outlet flow passage, said valve body having a valve seat surrounding the inlet flow passage, said body having an opening therein in alignment with the inlet passage and in communication with the inlet passage and with said at least one outlet passage, said body having a shoulder providing a shoulder seat surrounding said opening, an actuator sleeve adapted to be secured to said valve body, a shaft, means mounting said shaft in said sleeve to permit axial movement of said shaft in said sleeve, a diaphragm removably secured to said shaft, said diaphragm having a portion movable into engagement with the valve seat surrounding the inlet passage, diaphragm actuator means engaging said shaft for causing axial movement of said shaft for moving said diaphragm between open and closed positions with respect to said valve seat whereby in a closed position said diaphragm interrupts the flow of a liquid from the inlet passage through the outlet passage and in an open position permits the flow of liquid from the inlet passage to the outlet passage and means for preventing rotation of said diaphragm as said shaft is actuated to cause movement of said diaphragm between open and closed positions, said diaphragm having a portion engaging the shoulder seat which is retained in engagement with the shoulder seat during movement of the diaphragm between open and closed positions.
