Sterile Access and GMP
The Sterile Access port provides access to the interior of the valve body, at the lowest cross sectional point of the waterway, when the valve body is oriented at the optimum drain angle in a horizontal piping system. This port can be furnished utilizing a valve or with various tube extension lengths and end connections. This access port can be used as a sampling, condensate drain or divert port.
The GMP fabrication can be utilized to virtually eliminate dead legs in the design of point-of-use outlets in a typical WFI distribution loop. The process fluid flows through the valve body. As demand warrants, the valve is opened, providing an uncontaminated sample untainted by bacterial growth or contaminants which may accumulate in outlets greater than 6D. The outlet can also be utilized as a steam condensate drain or as a divert port. The valve body has been modified to accept a third port of the same diameter or smaller, positioned adjacent to the weir at the bottom of the valve.
