Washdown Solutions

Bimba provides a variety of standard actuation products designed specifically for use in wash-down applications. These actuators are manufactured using corrosion resistant materials such as 303 and 304 stainless steel and component designs with smooth contact surfaces that eliminate contaminant "catch points".  

Bimba's solution focused expertise can provide customized actuators to service unique environmental conditions and equipment geometries often required for food processing, dairy and marine applications.


Use the chart below as a guide to select actuator and other component materials compatible with your wash-down application.
