Selection Guide
Lined vs. Metal Valves
-
1
Choose lined valves when the process fluid is corrosive and must be isolated from the metal body.
-
2
Choose metal valves when temperature, pressure, abrasion, or mechanical strength is the main driver.
-
3
Correct selection depends on chemical compatibility, pressure class, temperature, and actuation needs.
For selection, share flow rate, discharge pressure or head, viscosity, temperature, solids content and installation conditions — our engineers will recommend the right valves configuration.
