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.
Some key features:
- 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
- Isolation achieved with two discs
- Nitrogen valve body pressurization
- No risk for operators to be exposed to hot gas
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.
Disc and seat design is unique - stellite hardfacing on contact areas, disc floating to accommodate thermal expansion, erosion prevention by sealing recessed design of sealing.
Two of IMI Remosa-made isolation valves have been tested by SGS for maximum seat leakage and certified according to ANSI/FCI 70-2-2006 (class V).
Optimized flow dynamic design guarantees undisturbed process flow and negligible power losses, with no erosion on sealing surfaces.
Our Double clapet isolation valve is operated by an IMI Remosa Hydraulic Power Unit. Open/Close sequence is implemented in the control unit.
