Flush sealing tank valve with diaphgram

A valve, comprising:

• a valve housing having an outer wall defining the first inlet to the valve, the first inlet having an inlet axis, the housing having an inner chamber and a first outlet, the first inlet and the first outlet communicating with the inner chamber;
• a valve body movably mounted in the housing, the valve body being movable along the axis of the first inlet at least partly through the inner chamber, toward and away from the first inlet;
• a diaphragm sealing across the valve chamber between the valve body and the first inlet, the diaphragm being movable by movement of the valve body along the axis of the first inlet, to seal the first inlet, and retractable to permit connection of the first inlet and the first outlet;
• means defining a second inlet to the inner chamber, the second inlet being disposed on a side of the diaphragm facing the first inlet, and means defining a second outlet located on an opposite side of the diaphragm from the first inlet, the second outlet defining a path for a sterilizing fluid;
• a shaft movable in a cylinder and connected to the valve body for advancing and retracting the valve body along the axis of the first inlet, the valve body defining an opening running parallel to the inlet axis and the valve body having a slot directed axially along an outer surface thereof, the second outlet being defined by a conduit extending radially of the axis into the slot.
