Yes! In many cases, we can ship your order on the same day it’s placed. We maintain a large in-stock supply of industrial-use Kunkle valves and parts for this purpose. In addition, military specification orders can be expedited on a case-by-case basis. Please contact us to learn more about how we can meet your specific needs.

Dante Valve merged its sister company – Danco Valve – into Dante’s operations, effective July 31, 2011. The transaction made Dante a manufacturer, as well as a distributor, of valves and related products. The two companies were combined to take advantage of operational efficiencies, which we, in turn, pass on to our customers as well.

Today, the Dante Valve brand is the exclusive manufacturer of Danco’s military specification pressure relief valves, which will continue to be marketed under the Danco Valve name. Danco Valve products are produced primarily for Navy and Marine applications. We maintain an extensive inventory of Danco Valve products that are available for immediate delivery.

Yes! At Dante Valve, we’re so confident in our quality that we offer a 2-year warranty* on all of our valves – whether new, reconditioned or repaired. To maintain the warranty, however, the valves must have the original seals intact and must not have been tampered with or opened.

*Excluding cases of customer negligence or abuse.

Kunkle Valve processes and then manufactures the valves only after you place your order, which means it can take several weeks for you to receive products. At Dante Valve, we maintain a large inventory of Kunkle valves and parts – so we can ship the exact valve you need on the same day you place your order, saving valuable time and keeping your operation on schedule.

Keep up with Dante Valve.
