ECO valves
Recently introduced dahl-ECO valves incorporate a new, ultra durable patented alloy called EcoBrass®. This alloy makes the valves the most corrosion-resistant on the market, exceeding all toxicity and performance standards. The EcoBrass alloy ensures that the new valves exceed lead-free requirements based on California AB1953 and Vermont S-152 legislation, and surpass any low lead standards worldwide. Also, dahl- ECO mini-ball valves surpass all corrosion resistance standards and they exceed the toughest performance standards including those set by CSA B125.1, ASME A112.18.1 and IAPMO. DAHL.
