Inlet control valve dampers...

are used primarily as fan inlet control dampers. The use of a radial vane damper enhances the performance of a fan by :

• Changing the fan curve as the damper moves
• Introducing swirl into the inlet of the fan in the direction of rotation
• Eliminating low-volume stalling of the fan

V.V.C. uses a heavy-duty linkage system by means of external bearing ring and ball-bearings at each shaft wich allow reliable and smooth operation. Valve blades are self suporting by internal bearing.

All type ICV-valves can be supplied with pneumatic or electric actuators and positioner.
