Lead-Free, Regulation Compliant Water Valves from ASCO and Mead O'Brien

Considerations for Solenoid Valve Selection

• Brass can have 2.5% lead content, so you must do a calculation to ensure compliance.
• Lead-free brass products are now available.
• Composite and plastic components are lead free.
• Stainless steel is lead free, but it remains expensive.
• NSF approved valves are often the preferred choice and may even be mandated in the future

Lead is extremely toxic. Tight US safety regulations affect manufacturers of products such as drinking water fountains, reverse osmosis systems, coffee machines. and commercial kitchen equipment. A lead-free system cannot contain soldering flux with greater than 0.2% lead content, or more than a weighted average of 0.25% lead in the wetted surfaces of pipes, pipe fittings, plumbing fittings, and fixtures. Under the law, lead free is a cumulative concept. Let's take an example. A manufacturer who makes dishwashers performs the lead content calculation, averaging all of the models relevant components. A brass valve has 2.5% lead content in the brass parts, well over the 0.25% limit. But the small wetted surface area of the valve is outweighed by the large wetted surface of the stainless steel tank with zero lead content. No design changes are needed to comply with the law.
