Valvola di isolamento a doppio battente

La valvola di isolamento a doppio battente di IMI Remosa presenta un design nuovo, brevettato per garantire una chiusura a tenuta ermetica nelle condizioni operative più estreme, comprese la temperatura e la pressione. Installata nell'unità di recupero della potenza di cracking catalitico fluidizzato (FCC), consente la manutenzione dell'espansore evitando l'arresto del 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.
