SC - Linear Damper Actuator
Precise pneumatic actuator for dampers, valves, and flow control.
Built-in lubrication system for maintenance-free operation.
Customisable stroke lengths for diverse applications.
Air-lock device for compact and efficient design.
Features
The SC series linear pneumatic actuators provide precise control of dampers, louvres, butterfly valves, and ball valves in power plants, refineries, pipelines, and marine environments. Built with aluminium alloy or corrosion-resistant carbon steel, they feature customisable strokes from 150mm to 300mm and cylinder diameters from 63mm to 420mm. A double-guide system ensures smooth, accurate operation without overshoot, while the built-in lubrication system eliminates the need for routine greasing. Designed for fast response times and maintenance-free operation, SC actuators deliver efficient, long-term performance in demanding flow control applications.
