ARA - Axial Rotary Actuator
Compact axial rotary actuator offering customised performance, reduced footprint, and reliable operation in tight spaces like offshore platforms.
Compact and lightweight design minimises facility footprint and skid sizes.
Customisable configurations ensure compatibility with various torque curves and valve requirements.
Durable construction with carbon or stainless steel materials withstands harsh industrial environments.
Features
The ARA actuator delivers efficient, customised performance, ideal for space-constrained environments such as FPSOs and offshore platforms. Its axial rotary design minimises the footprint while maintaining performance comparable to conventional actuators. Built with durable materials, it handles extreme temperatures, operates with air, oil, or spring, and suits on/off and modulating applications. Compliance with ATEX, PED, and SIL 3 standards ensures safe, reliable use in challenging conditions. Lightweight, easy to install, and cost-efficient, the ARA actuator is an excellent choice for tight installation areas, reducing skid size, weight, and overall project costs.
