The standard coating option for the Series 3R rack and pinion actuator is a hard anodized coating. The body is coated inside and out with epoxy-coated end caps. The carbon steel pinions are zinc plated, and all the fasteners are stainless steel. This standard coating is suitable for most general and industrial applications.
Electroless nickel plating is another actuator coating option. This coating applies externally and internally. Electroless nickel coating provides excellent corrosion resistance for acid mines or caustic wash downs with sodium or potassium hydroxide.
Another coating option is PTFE infusion, which is also applied internally. This coating is excellent in seawater applications as it can withstand an ASTM B117 salt fog spray test. PTFE infusion is also ideal for caustic washdowns with sodium or potassium hydroxide.
A marine epoxy coating option for the actuator body may also be added to other items, such as valves and gearboxes. This coating is an excellent preventer of corrosion in marine service environments and is available in custom paint colors to meet your specifications.
Another option is not a coating, but instead, the series S2 all stainless steel rack and pinion actuator. This actuator has an electro-polished finish and is an excellent economical solution to harsh chemical environments. It is ideal for the chemical-resistant requirements of the pharmaceutical, food and beverage, pulp and paper, and petrochemical industries. Series S2 actuators can be coupled directly to stainless steel valves and accessories to create a complete stainless steel automated package.
