ASEPCO Weirless Radial-Diaphragm™
Designed for critical aseptic processing applications
|The ASEPCO Weirless Radial-Diaphragm Tank-Bottom Valve is used as original equipment by the two largest U.S. bioreactor manufacturers, and it is experiencing growing popularity in the food and chemical industries. See the drawing to understand why the most forward-thinking engineers in aseptic processing have made ASEPCO valves a standard.||The Tank-Bottom Valve can be ported to allow it to be C/SIP or flushed while closed, providing access through the valve body to the downstream lines. The ability to quickly flush or C/SIP while the valve is closed solves downstream problems simply and speeds the product changeover.
