THE ORIGIN OF HAWK VALVE BEGAN WITH Herb Goelz A strategy of Mr. Goelz’s was to to buy available and valuable surplus marine and Navy valves and fittings. This unused surplus material was maintained in Jacksonville, FL by warehouse manager Mike Hawkins, nicknamed Hawk, the first employee. In the early days of the affair with surplus commodities, when someone needed a valve or fitting, they would say. “check with Hawk.” Furthering and building upon their father’s ambition, the Goelz Brothers decided to make the surplus enterprise its own standalone entity in 1996 and Hawk Valve, Inc was born. Hawk has the largest inventory in the world for specialty marine piping products for US ships and the Navy. Despite our humble surplus beginnings, we now also source factory new material from all over the world. And, if we don’t have it, we will find it or manufacture it ourselves. Hawk’s niche strategy of committing to inventory and its responsibility to customer service is truly what sets us apart and above all competition. Copyright 2021 © Hawk Valve, Inc.

Copper Nickel C715 is also known as Copper Nickel 70/30 (CUNI 70/30) because it is made up of 30% nickel or as ASTM B466 and ASME SB466. C706 is known for its moderate strength, weldability, and formability. The inclusion of controlled quantities of iron and manganese also give the 70/30 alloy an extraordinary resistance to general corrosion and stress cracking, as well as to erosion and impingement due to turbulent water containing air bubbles and silt flowing at high velocities. Due to the specific properties of nickel and copper alloys, they are applied in a variety of Navy, Commercial Marine, and Offshore industrial applications. C71500 COPPER NICKEL (CUNI) APPLICATIONS: Desalination materials Underwater tubing Heat exchangers Marine engineering Cupronickel( CUNI- Copper Nickel) is highly resistant to corrosion in seawater. For this reason, it is used for piping, heat exchangers and condensers in seawater systems. Copyright 2021 © Hawk Valve, Inc.
