ABSTRACT

11'e Navy spends millions of dollars each year maintaining valves of various types due to  erosion., corrosion, and other service-related problems. In addition, the current wide variety of  valve types used throughout the Navy results in over 60,000 allowance parts lists (APL's) (and  nearly 8,000 vendors) in the supply system which are cumber­ some and costly to maintain. Composite  technology offers the potential for signifi­ cant cost savings in maintenance due to  corrosion/erosion resistance. The appli­ cation of composite technology along with new valve  designs which minimize and standardi.ze valve component parts has the potential to significantly  reduce valve life-cycle costs. The Navy is developu,g a family of non-metallic composite ball valves, NPS O. 5- 12, for shipboard applications. A NAVSEA standard drnwing will be issued for procurement  purposes. The benefits of this valve design are reduced life cycle cost through significantly  reduced main­ tenance and supply support; reduced weight; compatibility with all piping, and  potential reduction in costs assot.iated with valve APL's, due to increased standardization.   Selected sizes have been prototyped for laboratory and ship­ board tests and evaluations IT&E).
