ITT Aseptic barrier and block bodies

ITT Pure-Flo custom integrated block valve.

A custom Pure-Flo block valve combines multiple diaphragm-valve weirs and internal flow paths in one machined body built around the process P&ID. Replacing a cluster of standard valves, tees, and welds can reduce hold-up volume, dead legs, installation space, and validation work while preserving the required valve functions.

What ITT Pure-Flo custom integrated block valve is—and where it fits.

A custom Pure-Flo block valve combines multiple diaphragm-valve weirs and internal flow paths in one machined body built around the process P&ID. Replacing a cluster of standard valves, tees, and welds can reduce hold-up volume, dead legs, installation space, and validation work while preserving the required valve functions.

Where it fits

Where it fits

Use a custom block when no standard ITT configuration matches the routing, orientation, drainability, or equipment envelope. Selection starts with the P&ID, flow paths, valve sequence, available space, cleaning method, fabrication orientation, and documentation package—not with a catalog part number alone.

What to confirm

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

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.

02 - Selection

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 pointWhy it mattersTriplex note
Process purposeShutoff, 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-upDead 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 diaphragmThe 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.
03 - Resources

Manufacturer literature and related Triplex resources.

Use these documents as a starting point, then confirm final selection against the actual process conditions.

04 - Related

Keep the selection connected to the full ITT valve platform.
