Louver and Damper Control with Vane Actuators

Besides pneumatic valve actuation, Kinetrol vane actuators are used widely on controlling industrial and commercial louvers and dampers.

The video below gives you a short visual demo of a louver being opened, closed and positioned with a Kinetrol vane actuator and electro-pneumatic positioner.

Louvers and dampers are used to stop or regulate the flow of air inside a duct, chimney, air handler, or other air handling equipment.

Some varieties of dampers are:
  • Louvered Inlet Box Dampers
  • Radial Inlet Dampers
  • Variable Inlet Vane (VIV) Dampers
  • Vortex Dampers
  • Discharge Dampers
Industries that use dampers include:
  • Petrochemical
  • Oil & gas
  • Power generation
  • Construction industries

Pneumatic Actuators in Marine Environment (Offshore Rigs)

Kinetrol in Marine Environment
High density, cramped spots are ideal
for Kinetrol actuators and accessories.
Offshore oil rigs present some special challenges to pneumatic actuator manufacturers. First, the corrosive marine environment takes a harsh toll on the internal and external parts of a typical actuator. Rack and pinion actuators are particularly susceptible.

Because rotary vane actuators, (such as Kinetrol) or their spring units, don't "breathe" ambient air, they have great immunity to internal corrosion. Also, a very durable, epoxy enamel finish and stainless steel hardware provide maximum external protection.

Ideal for corrosive, marine installation.
Another challenge for offshore use is the very limited space available. Facilitation of large scotch yoke actuators, is quite difficult. Actuators such as Kinetrol's compact vane design with integral direct-mount limit switch make it a perfect choice in applications where space is at a premium. In these cramped and below grating installations you want the long maintenance-free life that you can install with confidence for years of service.
