The AKS actuator series** for tank valves is a durable, easy to maintain actuator made of a plastic housing and stainless steel diaphragm interface. The resulting actuator is a hygienic design which is GMP-compliant.
Our tank valve actuators are also available in the AJS actuator series an all stainless steel actuator providing all the same performance, but in a heavy-duty package.
Both versions offer manual and pneumatic options, are provided with laser-etched serial numbers for traceability, and carry a market-leading three year warranty. It is straightforward to add automation to the pneumatic versions by mounting switches or controllers from any manufacturer.
Work with all manufacturers linear switches and controllers (i.e. Westlock, Stonel, Burkert, etc.)
**AKS actuator series only available on 0.5" to 1.5" sizes
Multiple materials cope with virtually every temperature, pressure and chemical challenge in the food and biopharm industries.
Materials include:
All diaphragms are laser-etched with cure dates and batch numbers, ensuring that they are completely traceable.
