Aseptic sampling valve having a valve body with a generally cylindrical side wall and a relatively thin, generally planar end wall, an inlet opening in the end wall, a valve seat surrounding the inlet opening, a port opening through the side wall and extending toward the inlet opening at an acute angle relative to the axis of the valve body, and a valve member movable axially within the valve body between open and closed positions relative to the valve seat for controlling communication between the inlet opening and the port.

Aseptic sampling valve

A mixer for an aseptic liquid in a vessel having a wall comprising a weldment post having a distal extremity inside the wall and having a proximal extremity outside the wall. The weldment post has a bore therein extending out through the proximal extremity of the weldment post. A motor driven magnet drive assembly is disposed in the bore in the weldment post. A hub carrying impellers is rotatably mounted on the weldment post. A magnet driven assembly is mounted in the hub and is disposed in close proximity to the magnet drive assembly but is separated therefrom by a liquid-tight seal. The magnet drive assembly includes a plurality of circumferentially spaced apart driven permanent magnets which are caged by bars to prevent movement of the driven permanent magnets with respect to the hub.

Mixer for aseptic liquids

An inline process valve assembly having a valve body of a rigid material having a thru bore which is circular in cross-section forming a flow passage extending through the valve body along a longitudinal axis and having a lower arcuate surface. A cone-shaped recess is formed in the body and has a central vertical axis extending perpendicular to the longitudinal axis. The cone-shaped recess opens into the flow passage and has an hemispherical rounded nose which is generally coincident with the lower arcuate surface of the flow passage. A cone-shaped diaphragm of a flexible material disposed in said cone-shaped recess and is movable between open and closed positions with respect to the flow passage. The diaphragm has an outer margin. A clamp is provided for clamping the outer margin of the diaphragm to the valve body to form a liquid-tight and air-tight seal between the diaphragm and the body. An operator is secured to the diaphragm for moving the diaphragm between said open and closed positions.

Inline process valve assembly

An aseptic valve construction including a valve body having an inlet flow passage and at least one outlet flow passage. The valve body has a valve seat surrounding the inlet flow passage and has an opening therein in alignment with the inlet flow passage and in communication with the inlet flow passage and with the at least one outlet flow passage. A shoulder providing a shoulder seat surrounding the opening is provided in the valve body. A diaphragm is disposed in the valve body and has a surface adapted to be moved into engagement with the valve seat and another surface in engagement with the shoulder seat. The diaphragm has a cylindrical portion extending between the surface engaging the valve seat and the surface engaging the shoulder seat. The cylindrical portion has a length and a constant inner diameter and a constant outer diameter along its length for preventing the cylindrical portion from buckling or wrinkling. A method for operating the aseptic valve construction of the present invention is provided.

Aseptic valve construction with diaphragm having straight neck

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.
