AMM715 radial vane butterfly valve for flue gas
Product information
The AMM715 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 metal as standard and are suitable for operating pressures up to 0.5 bar. This series of flue gas valves is designed to allow the finest possible regulation. The valve is designed so that the stuffing box gasket pusher and bolts are not subject to 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 radial vane butterfly valve for flue gas type AMM715 is commonly used for flue gas systems with a relatively low operating temperature where very precise regulation of the process is sought. These valves are fully customizable 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.
