14 PROCESS FABRICATIONS
GMP TM
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. Typically the GMP Valve is oriented in
the vertical position. For horizontal process applications, the sterile
access valve is recommended. The GMP configuration is available in
sizes 1/4"–4" (DN 8–100) and can be supplied with buttweld or ferrule
end connections.
STERILE ACCESS PORTS
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 as shown 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. This fabrication is
available in 316L stainless steel forgings, 1/4"-3" (DN 8-80) or investment
castings, 2-1/2"-4" (DN 65-100).
STANDARD ZERO STATIC WITH “U” BEND
The Standard Zero Static fabrication is typically oriented as shown
below and has excellent application properties in sampling, draining or
diverting process fluids. The inherent dead leg, defined as the distance
from the tubing/piping centerline to the valve weir, is minimized to
comply with the FDA 6D guidelines in all possible size configurations.
This fabrication is available in 316L stainless steel investment cast
2-1/2"-4" (DN 65-100) or forged valve bodies, sizes 1/4"–2" (DN 8–50).
ZERO STATIC “T” WITH “U” BEND
The Zero Static “T” fabrication is a design modification of the
Standard Zero Static, by significantly reducing the dead leg and area for
product entrapment. The Zero Static “T” fabrication is optimally used in
sampling, draining or diverting applications of critical process fluids.
This fabrication is available in wrought 316L stainless steel 1/2"-2"
valve (DN15-50) by 4" (DN100) header maximum.
