The Bronze Valve is traditionally made of a mixture of copper and tin. It is more resistant to cracking than something like iron, is malleable, and can be cast or machined into valves and other components. Bronze has many benefits, including high ductility (resists cracking), corrosion resistance, and low cost. They are used in Residential and Commercial Plumbing, Water Well, HVAC and many other applications. The bronze is fairly inexpensive, extremely ductile, and is great for resisting corrosion, particularly from any corrosives similar to seawater. The offered Bronze Valve is very efficient and easy to install.
