The Naval Nuclear Laboratory is interested in means of directly operating a large water flow isolation valve electrically or electromagnetically (valves for pipes 4-20 inches in diameter). Cycle time for opening or shutting the valve must be within 30 seconds. The valves must be hermetic (without the need for valve packing or other degrading approaches for providing hermeticity). Valves must shut against a head of up to 2500 psi of water at an operating temperature as high as 600 F. Valves requiring cooling of the operator are acceptable but not desired. When shut, the valve must be capable of withstanding a 2500 psi differential pressure. The valve is to be opened with pressure less than 20 psi. Proposals will be accepted for use of existing products and developmental efforts. Update: 4/6/2021: Updated Request for Proposal document (Rev. 2) correcting the contact information for FMP-NNL-006.
