Bidirectional Round Damper
Bidirectional Round Damper Butterfly Valve
Round damper butterfly valve, with bidirectional design.
Designed for pneumatic transport of air or gases at different temperatures.
Option of manufacturing “WAFER” type or with bored flanges.
Watertight integrity between 97% and 99%.
From DN 80 up to DN 3000 (larger sizes on request).
Check for the general dimensions of a specific damper butterfly.
WORKING PRESSURES (ΔP):
The most significant difference between the ML and MF series is the differential working pressure (ΔP).
For lower pressures, choose the ML series (Light Butterfly);
For higher pressures, choose the MF series.
Maximum standard work pressure is 0.5 kg/cm2; greater pressures upon request.
These butterfly damper valves are suitable to work with a wide range of air and gases. They are particularly suitable for controlling the flow of gas in pipelines. Used mainly in:
- Cogeneration plants
- Electrical power stations
- Energy sector
- Thermal power stations
- Chemical plants
Pressure Equipment Directive: (PED) ART 4.3 /CAT.1. • Explosive Atmospheres Directive: (ATEX) CAT.3 ZONA 2 and 22 GD.
All valves are tested at CMO valves and material and testing certificates can be supplied on request. The watertight integrity of the seat area is measured with gauges.
