The United States Coast Guard requires 44 units of a specific ball valve (Part Number V8814ZH, formerly NSN 4810-01-517-8110) for use on its 87-foot patrol boats. The brand name part from Virginia Electronic Systems, Inc. is mandatory, though offers of "equal" products may be considered if they meet all specifications. The packaging and marking requirements are strict and non-commercial, with rejection of non-conforming items. The award will be a firm fixed-price contract based on the lowest price technically acceptable offer. All responsible sources registered in SAM.gov may submit a quotation.
