Selection guidance
Protection starts with the application—not the part number.
The right device depends on the scenario it must protect, the media moving through it, and the pressure and temperature conditions around it. TVI helps turn those variables into a defensible selection.
Define the scenario
Blocked flow, fire, thermal expansion, tube rupture, or normal tank breathing each creates a different requirement.
Understand the service
Steam, air, gas, vapor, liquid, and two-phase flow affect sizing, trim, materials, and certification.
Validate the conditions
Set pressure, temperature, back pressure, capacity, connections, and available installation space all matter.
Plan for the lifecycle
Documentation, repairability, inspection history, and future replacement should be considered before purchase.
Beyond the catalog
Products are only useful when they fit the process.
TVI connects selection, supply, service, and asset visibility so the equipment you buy is easier to install, maintain, and replace.
Sizing + validation
Application review and sizing support help confirm capacity, media, materials, certifications, and operating conditions before the order is placed.
Certified repair
Three certified VR shops, National Board-approved quality processes, and local repair access support the equipment after installation.
Asset visibility
Connect product records, repair history, inspections, and future service needs so your team can plan with fewer surprises.
