Considerations for Solenoid Valve Selection
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.
ASCO Series 212 Composite Valves: are designed for use in potable water applications and come with NSF certifications. Installation is made easy through the FasN system, with multiple end connector options.
ASCO Series 210 Solenoid Valves: ASCO has introduced new lead-free brass solenoid valves to the market that are aimed at providing a safer alternative to standard brass valves. The new products meet the EPA’s Safe Drinking Water Act Section 1417 low lead requirements.
