FAQ - Fluid Catalytic Cracking (FCC)

Fluid Catalytic Cracking (FCC) – Recommanded valve :

The main requirements of FCC applications are :
– resistance to abrasion
– high temperature suitability
– long life and reliability

Guichon produces valves with all weldable high temperature materials, also ceramic, concrete and full stellite linings allowing for longer service and improved safety.
