Pneumatic Actuators Well-suited for Offshore Valve and Damper Applications

Offshore Platform

Offshore oil rigs present special challenges for valve and damper actuators, namely high vibration, limited space, and salt-laden atmospheres.

Corrosion

Corrosion resistant housing
and sealed spring.

Corrosive marine environments takes a harsh toll on the internal parts of actuators. Continuous exposure to salt quickly corrodes the external housing and inevitably enters the actuator and corrodes the internal springs and gears.

Vibration
Constant structural vibration, caused by the dynamic forces generated by compressors, pumps, and engines, leads to poor equipment reliability and eventual failure. Pulsating and shaking forces expedite wear on mechanical connections such as gears and yoke mechanisms, with many gear failures due to resonant vibration.

Space
Oil platform actuators, control valves, safety valves, and piping systems are configured very similarly to their terra firma cousins, with the major difference between land and platform equipment being reduced weight and size. Space is at a premium and it is critical to keep equipment as compact as possible.

Single moving part.
No gears or yokes.

A Better Alternative for Marine and Offshore
Kinetrol rotary vane actuators provide an excellent solution, well-suited for off-shore and marine applications. A durable epoxy stove enamel finish and corrosion resistant zinc (non-incendive) or aluminum alloy case protect the actuator from the harsh environment.

Size comparison for similar output.

The integral vane/shaft casting (a single moving part) and space filling/energy absorbent sideplates (polymer or metal) protect the actuators from the vibration, shaking, and shock.

Finally, Kinetrol vance actuators only require 1/3 to 1/2 the required installation space of similarly equipped rack and pion actuators.

Pneumatic Actuators in Marine Environment (Offshore Rigs)

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.
