INTR ODUCTIONExper ience gained since 1987, s ucces sful ly des igning and manufactur ing valves for operation directly immer sedin sea water , has been applied to develop B ifold F luidpower ‘s extens ive r ange of technically super ior sub- seavalves . Des igned to operate reliably on fluids with contamination levels g reater than NAS1638 Class 12, thesetr ue fails afe valves br ing you the options for reducing sub- sea contr ol module s ize, weight and costs , and putwor ld beating performance at your command.B elow are typical specification requirements for sub- sea valves and comparable B ifold F luidpower valveperformance:
