ITT Pure-Flo sterile tank-vent filter shunt.
The DV2WS sterile filter shunt is a two-way divert assembly that connects one tank vent nozzle to two vent-filter housings. It lets the system switch between filters without interrupting tank operation; available traced arrangements add condensate-drain valves for steam-sterilized filter housings.
What ITT Pure-Flo sterile tank-vent filter shunt is—and where it fits.
The DV2WS sterile filter shunt is a two-way divert assembly that connects one tank vent nozzle to two vent-filter housings. It lets the system switch between filters without interrupting tank operation; available traced arrangements add condensate-drain valves for steam-sterilized filter housings.
Where it fits
Use it on continuously operated WFI or other high-purity storage tanks that require redundant vent filtration. Confirm filter-housing arrangement, sterilization method, condensate management, port orientation, actuation sequence, and any steam-tracing requirements.
What to confirm
Valve size, end connections, orientation, drain angle, material, surface finish, diaphragm material, actuator or bonnet style, and documentation expectations should all be checked before quoting.
How Triplex helps
Triplex helps translate the process problem into a practical ITT body selection so the valve package fits the line, the cleaning method, and the maintenance plan.
What Triplex will want to know.
Good valve recommendations come from process context. A few details up front prevent a lot of expensive back-and-forth later.
| Selection point | Why it matters | Triplex note |
|---|---|---|
| Process purpose | Shutoff, sample, purge, drain, divert, tank outlet, or aseptic barrier duty changes the correct body geometry. | Start with what the valve has to do in the process, not just the valve size. |
| Cleanability and hold-up | Dead legs, drainability, and internal volume can matter as much as pressure and temperature. | Send sketches or photos when the valve location is part of a skid or vessel connection. |
| Topworks and diaphragm | The body decision should be made with bonnet/actuator and diaphragm material in mind. | Triplex can help pair the body with manual or pneumatic operation and the right diaphragm review. |

Use these documents as a starting point, then confirm final selection against the actual process conditions.
Keep the selection connected to the full ITT valve platform.
