Our range of stainless steel actuators, pneumatic and hydraulic, includes Double scotch yoke, Single scotch yoke (heavy duty) and heavy duty linear cylinder. They are particularly suitable for corrosive offshore or onshore environments, commonly found in Oil and Gas, Mining and Chemical sectors.
All models are entirely 316 grade stainless steel, but in cases of extreme corrosion can also be painted with an offshore epoxy paint.
For high corrosion environments, Ascendant always recommends fitting an enclosed breather system on the actuator to ensure that the corrosive atmosphere cannot affect the inside components of the Actuator where corrision cannot be seen.
