The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support MECH, is seeking to procure a diaphragm valve under a presolicitation notice. The requirement includes one unit of NSN 7H-4820-015803822, with delivery terms set to FOB origin, and the government intends to negotiate with only one source due to the unique nature of the item. This valve is critical for various defense applications, and the government has determined that it is uneconomical to reverse engineer or procure data rights for this part. Interested parties are encouraged to express their interest and capability to fulfill this requirement, with quotes being accepted prior to the award date. For further inquiries, potential vendors can contact Joshua Eshleman at (717) 605-6055 or via email at joshua.j.eshleman@navy.mil.
