DEVELOPMENT AND TESTING OF THE ROBOVALVE; FINAL REPORT

This faucet valve was developed to meet specific requirements: low cost, capable of local manufacture, essentially leak-proof, suitable for use in both public and private hydrants, self-closing, absolute minimum of moving parts, parts which have insignificant monetary value and therefore not subject to pilferage. Contains description of the robovalve; discussions of experimental work; manufacturing process for the robovalve; and conclusions and recommendations. Includes illustrations and tables enumerating wear characteristics and leakage. Appendices provide review of plastic and elastomer materials, working drawings of public and household robovalves and a plastic water container, and series of photographs of robovalves.
