Frequently Ask Questions
A stainless steel pneumatic actuator uses compressed air to generate rotary motion for automatic valve operation. Its stainless steel construction provides excellent corrosion resistance.
SS316 generally provides better resistance to chlorides and aggressive chemicals than SS304. The appropriate grade depends on the operating environment.
Yes. Stainless steel construction makes these actuators suitable for hygienic environments, particularly when the required material grade and surface finish are specified.
They are used to automate ball, butterfly and plug valves in corrosive, hygienic, and demanding industrial applications.
Alis Valves manufactures and supplies stainless steel pneumatic actuators for industrial valve automation with different torque ranges, materials, and control configurations.
Most industrial pneumatic actuators operate within approximately 3–8 bar, depending on the actuator model and required torque.
