Isolation Valves

Double clapet isolation valve

IMI Remosa’s double clapet isolation valve is a new patented design to guarantee a tight shut-off under the most extreme operating conditions, including temperature and pressure. Installed in the Fluidised Catalytic Cracker (FCC) power recovery unit, it allows the maintenance of the Expander while avoiding the shut-down of the FCC.

Tight shut-off.
Innovative metal to metal seal design.
Operates in extreme process conditions.
Negligible energy losses.
Hot or cold wall design.
Full metal construction.

Benefits of Isolation Valves

When the valve is installed in the FCC’s power recovery unit its innovative, patented design isolates the line so that maintenance can be carried out on the Expander without shutting down the FCC.

Unique disc and seat design – Stellite hardfacing on contact areas, disc floating to accommodate thermal expansion, erosion prevention by sealing recessed design of sealing and Class V leakage certified.
Double clapet – Isolation achieved with two discs, nitrogen valve body pressurisation with no risk for operators to be exposed to hot gas.
Optimised flow dynamic design – Undisturbed process flow, negligible power losses and zero erosion on sealing surfaces.
Operated by IMI Remosa Hydraulic Power Unit – Open/Close sequence implemented in the control unit.
