Pure-Flo®

PURE-FLO ® DIVERT VALVES
The patented Pure-Flo Divert Valve is the first
diaphragm-style divert valve ideal for applications
involving the diverting or mixing of process fluids. Key
advantages to this design are as follows:
• The Pure-Flo Divert Valve reduces dead leg typical
in diverting applications utilizing two conventional
diaphragm valves.
• The Pure-Flo Divert Valve utilizes a diaphragm valve
design, which has long been regarded as the most
cleanable and sterilizable valve type within the
Pharmaceutical and Bioprocessing Industries.
• The overall number of system welds is reduced
utilizing the Pure-Flo Divert Valve in comparison to
independent valves welded to form an assembly.
• The Pure-Flo Divert Valve is manufactured from
316L stainless steel and is available in a variety of
end connections and piping configurations to best
suit your system design.
• The Pure-Flo Divert Valve is a patented design; US
patent numbers are as follows: 5,273,075;
5,427,150 and DES # 362,294.
APPLICATIONS
The Pure-Flo Divert Valve, the first divert valve to
incorporate the diaphragm valve design, is available in
2-, 3-, 4-, 5-, and 6-Way configurations for the diverting
or mixing of process fluids. This unique design
significantly reduces contact surfaces and hold up volume
inherent to multiple valve assemblies, hence
increasing the cleanability and sterilizability of the
valve while minimizing the potential for process fluid
contamination.
The Pure-Flo Divert Valve is ideal for challenging system
designs where space is a premium. By significantly
reducing the overall space envelope inherent to typical
header and branch valve assemblies, the Pure-Flo
Divert Valve provides greater flexibility to the system
designer.
BENEFITS
• Cleanability and sterilizability are enhanced with the
Pure-Flo Divert Valve. It is recognized throughout
the Pharmaceutical and Bioprocessing Industries as
the most cleanable and sterilizable valve available.
• The 2-Way Pure-Flo Divert Valve may be positioned
in a horizontal or vertical line, and is designed to
optimize drainability*.
• The 3-, 4-, 5-, and 6-Way Pure-Flo Divert Valve is
available with a sight glass, which allows the use of
optical scanners to measure characteristics of the
process media such as cell density and turbidity.
• Manufactured from 316L stainless steel, the Pure-
Flo Divert Valve is available with Certified Mill Test
Reports to assist in the validation process.
• Various inlet and outlet tubing configurations are
available in either buttweld or Tri-Clamp ® end connections
to allow for flexibility in system design.
• Manual or actuated, the Pure-Flo Divert Valve is
available with the process proven Pure-Flo manual
bonnet assemblies and the Advantage actuator. All
components are compliant with FDA material
requirements. Complete assemblies are pneumatically
seat and shell tested in accordance with MSS
SP-88.
• Available in sizes 1/4" - 4" (DN 8 - 80).
The 2-Way Pure-Flo Divert Valve is a patented design.
The Multi-port Divert Valve, 3-, 4-, and 5-Way design
is patent pending.
* The slope of process piping systems must be
designed to provide proper pitch in order to optimize
drainability. Drainability in a process system is
ultimately the responsibility of the system designer
and/or user.
