​​​​​​

Slide valves for fluid catalytic cracking (FCC) and flue gas lines​

Our slide valves are custom-designed and engineered to meet the severe and harsh conditions in the FCC Reactor and Regenerator control loop: Spent Catalyst; Regen Catalyst; Cooled Catalyst; Recirculation Catalyst; and Flue Gas Double Disc.


Key features​

  • Designed and tailored to customer specifications
  • Integrated IMI Remosa Control System with Actuator and Hydraulic Power and Control Unit
  • Hot wall and cold wall design options available
  • Custom design able to fit in existing units without the need of major structural reworks
  • Proven and reliable design with hundreds of installations worldwide
  • Approved by all FCC Process Licensors







​Benefits​



Cold wall single disc slide valve (Top view)

  • IMI Remosa Slide valves are designed for easy maintenance

    • All components that are subject to erosion and wear are easily replaceable. 

  • ​​All body mounting surfaces are CNC machined in order to allow a precise matching of the components during the assembly stage 

  • Erosion and temperature are the most critical issues for this kind of application, the best available materials are used to protect the main components

    • The materials are applied in house by our own highly skilled employees 

    • ​Special high-end alloys are used to manufacture the components subject to the most critical stresses

  • The manufacturing process has an uninterrupted quality control workflow from procurement to final testing

    • A state of the art Finite Element Analysis of the complete valve body is used to check the structural reliability against pressure, temperature and line loads.

  • Flow-dynamic behaviour of the valve in complex layout lines can be assessed in detail using computational flow dynamics simulations
