2. Type K Damper Drives have everything you’re looking for!
Experience with innovative solutions for all
your drive needs
Type K Damper Drives are designed, engineered, and manufactured
to provide unique solutions to meet the expanding needs of industry.
Type K offers a wide variety of pneumatically actuated drives designed to
meet the expanding needs of industry. Drives are available in two basic
styles, direct-mount (with custom-made brackets and couplings
provided), and a pedestal style designed for location on existing surfaces.
This is a typical
Direct-Mount style
drive. Type K offers a
wide variety of designs
and can customize to
meet any requirement.
Type K offers custom
mounting brackets
and shaft couplings to
meet any need.
This is a typical Pedestal Mount
style drive. All Type K Damper
Drives are available in 7 torque
ranges and can operate using air
supply pressures from 40 to 150
psig. Pedestals can be custom
designed to meet any need.
Available options include:
• Fail-in-place on loss of signal
• Fail-in-place on loss of air pressure
• Independent drive position feedback
• Travel limit switches
• Manual operators (handwheel & handlever)
• High-temperature (to 300ºF) construction

Rotork Type K rotary pneumatic damper drives are offered in two basic configurations; the PM Series (Pedestal Mount) and the DM
Series (Direct Mount). Both Series provide accurate quarter-turn control to dampers on combustion air and flue gas applications.
They offer modulating control, isolation open / close control and bus network control to fit your operating needs.
• Improved damper operation – higher torque output with same footprint
• 100% duty cycle, rated for continuous modulating service
• High torque / high speed – up to 20,800 lbf.ft with stroke speed as low as 3 seconds full scale
• Easily serviced with ‘open frame’ design
• Excellent in harsh, high-temperature environments
• Virtually zero air bleed in resting state
• “Drop-in-Place” retrofit eliminated field engineering, speeds up installation
With a Type K retrofit damper drive:
• The drive shaft and drive lever are in the exact same place relative to the floor mounting bolt holes
• The base and mounting holes will match the existing drive
• The lever will be dimensionally identical to the existing lever and will rotate through the same arc
• No costly field design or fabrication
• Complete field support offer by the extensive Rotork Site Services global network
