AMM701 butterfly damper for flue gas
Product information
The AMM701 butterfly valve is a valve for flue gas up to a maximum operating temperature of 200ºC. Flue gas systems are characterized by low operating pressures so these valves are manufactured from sheet material as standard and are suitable for operating pressures up to 0.5 bar. This series of flue gas valves is fitted with a standard bonnet and bracket making it unsuitable for insulation. The valve is designed so that the stuffing box packing pusher and bolts are not subject to the temperature in the pipe, allowing the stuffing box packing 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 IIANSI/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/FCI70-2 (zero leakage)

Application
The butterfly valve for flue gas type AMM701 is mostly used for air and flue gas with a relatively low temperature where the medium has little or 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.
