Introduction
Experience gained since 1987 of successfully applying valves directly immersed in sea water has been applied to develop the technically superior, market leading performance FPS10 range of shearseal type directional control valves. Fully seawater compatible, the standard products are able to operate on fluids with contamination levels greater than NAS 1638 Class 12. True failsafe valves, they bring you the benefits of reduced manifold weight, size and costs, and put world beating performance at your command. Below are typical specification requirements for sub-sea valves and comparable Bifold Fluidpower valve performance.
