Recently we found that the valves in the off gas (that comes from Vacuum distillation tower) separator unit line did not last long. After 6-7 months valve seat or body sprung leaks due to off gas. Please help me by suggesting the appropriate valve for this service.

Identification of the root cause of the leaks (corrosion or erosion) will help in addressing the issue with suitable material of construction.
