English Siemens butterfly valves in intermediate flange design, e.g., for installation in gas lines.
• Through-flow valve
• DN 80
• Effective angle of rotation 5…85°
• Suitable for gases of families I...III, air, and flue gas up to 180 °C
• Includes coupling for D-shaft Ø10 mm and mounting plate ASK33.1
• To increase the throttling authority, the throttle valve can be installed in the next larger nominal size
• Installation in ISO 7005-2 (PN10/PN16) and ANSI flange connections
Area of application
In combustion plants as a control device, e.g.:
• As a gas control damper
• As an air control damper
• As a flue gas damper for exhaust gas recirculation
• For applications with a large control range
• Suitable for mildly aggressive biogases and recycled gases
Type: VKF10.080PED, suitable for flange sizes DN80 and DN100
