AMM710H single louvre valve for flue gas
Product information
The AMM710H single louvre valve is a valve for flue gas up to a maximum operating temperature of 600ºC. Flue gas systems are characterized by low operating pressures so these valves are manufactured from sheet metal as standard and are suitable for operating pressures up to 0.5 bar. This series of flue gas valves features an extended bonnet and bracket making it suitable for insulation. The valve is designed so that the stuffing box gasket pusher and bolts are not subject to the temperature in the pipe, allowing the stuffing box gasket to be serviced from the outside at all times (outside operation).
Depending on the design, different leakage rates can be achieved:
- No seat: rate I ANSI/FCI 70-2 (= relative tightness)
- Metal to metal seat: rate II ANSI/FCI 70-2 (leakage = 0.5% x Kvs)
- Soft seat: rate III ANSI/FCI 70-2 (leakage = 0.1% x Kvs)
- Compressed air system: rate VI ANSI/FCI 70-2 (zero leakage)

Application
The single louvre valve for flue gas type AMM710H is mostly used for air and flue gas with a medium to high temperature where the medium has little to no contamination. These valves are fully adaptable to your requirements.
Standard part of the delivery is a general arrangement drawing and a 3D file for approval. After approval of the proposed design, we will start production. This avoids surprises and guarantees that valves can always be fitted appropriately.
