Kinetrol Dmper Dive Asembly with Positioner for Control

 Problem: steel mill was having numerous problems with bailey damper drives on balancing air control of exisiting dampers. Problems were:

1.        Exisiting drives unreliable for control, a lot of slop and play - (hysteresis).

2.        Dirty plant atmosphere would damage and foul internals of damper drive.

3.        Numerous belts, drives and miscellaneous parts made maintenance and repair a nightmare

 Solution: Knetrol actuator mounted to fabricated stand with same footprint as Biley damper drive.  New unit a hit !!!

1.        Direct mount positioner eliminates  linkage from positioner to actuator, direct mount gives tight control from output shaft of positioner to shaft of damper itself. A true one to one movement of damper with positioner.

2.        Sealed actuator and positioner a lot more tolerant of poor quality plant air and harsh environment.

3.        One moving part in the actuator (vane) makes for long trouble free life.

 Current status:  customer replacing dampers one at a time during planned outages.    This unit has a model 149 kinetrol actuator which has a torque output of  9,600 “ / # ‘s at 80# supply air.
