Selection Guide
Lined vs. Metal Valves
Selection Point 1
Choose lined valves when the process fluid is corrosive and must be isolated from the metal body.
Selection Point 2
Choose metal valves when temperature, pressure, abrasion, or mechanical strength is the main driver.
Selection Point 3
Correct selection depends on chemical compatibility, pressure class, temperature, and actuation needs.
