Since January 4, 2014, federal law has generally limited lead to a 0.25% weighted average across the wetted surfaces of plumbing products, including valves, that are used to convey water for human consumption. The old limit was 8%. That amendment to the Safe Drinking Water Act (Public Law 111-380) made most of the brass valves then sitting in American supply houses illegal for potable service, and a decade on, we still take calls from buyers who can't tell a compliant valve from a code violation. This guide covers some of the best potable water valves we recommend, the certifications that actually govern them, and when the water chemistry justifies spending up on a DZR brass ball valve or 316 stainless.
What "Lead Free" and NSF 61 Actually Mean on a Potable Water Valve
Compliance comes down to two separate certifications plus a legal lead limit, and buyers mix them up constantly.
NSF/ANSI 372 certifies lead content. A listed product's wetted surfaces average no more than 0.25% lead, which is the SDWA threshold. NSF/ANSI 61 is a different test entirely. The finished product, seats and seals included, goes through leach testing to confirm nothing harmful migrates into the water. In a more official way of putting it, the finished product and its water-contact materials are evaluated under highly exact conditions for contaminants that could leach into our drinking water.
A valve can pass 372 on lead and still fail 61 if a seal compound leaches something it shouldn't. For potable-water applications, verify the approvals required by the governing code and authority having jurisdiction. In most valve specifications, NSF/ANSI/CAN 61 health-effects certification plus NSF/ANSI/CAN 372 lead-content certification is the appropriate target.
The practical mistake we see: a buyer orders standard brass because the price is right, installs it on a drinking water line, and fails inspection. C36000 brass runs roughly 2–3% lead. That's well under the old 8% cap and far over today's 0.25%. The metal looks identical to a lead-free alloy. The only way to know is the certification stamp and the paperwork behind it. Not all conventional brass valves use C36000, so verify the exact alloy and product certification rather than judging by appearance.
If you're still weighing material before you even get to compliance, our breakdown of PVC vs brass ball valves covers where each belongs. And the reasoning behind the whole lead-free shift is worth reading in Going Lead Free — It's More Than Just a Trend.

Lead-Free Brass Ball Valves
For most building potable lines, a lead-free brass ball valve is the workhorse. Full-port designs keep the bore close to the nominal pipe size, so pressure drop stays low and your Cv stays high. A 1" full-port ball valve flows noticeably more than a reduced-port valve of the same size, which matters on long runs and booster-pump service.
Look for both the NSF/ANSI 61 and 372 marks on the body or in the submittal. Typical lead-free brass ball valves carry a 600 WOG (water, oil, gas) cold working pressure rating and a 150 psi saturated steam rating, with threaded or solder ends. Blowout-proof stems and PTFE seats are standard on the valves worth buying.
Apollo 94ALF-109-01A Ball Valve
The Apollo 94ALF-109-01A is appropriate for potable-water service because it is a lead-free forged-brass ball valve certified to NSF/ANSI/CAN 61 for drinking-water system components and NSF/ANSI 372 for lead-content compliance. Its full-port design maintains a near-unrestricted flow path, minimizing pressure loss in larger water lines, while the 316 stainless-steel ball, PTFE seats and seals, and corrosion-resistant lead-free brass body provide durable shutoff performance in treated-water plumbing.
This two-piece, bi-directional valve has NPT threaded ends and a -20°F to 366°F operating-temperature range. Special features of the Apollo 94ALF-109-01A include a quarter-turn lever for fast manual isolation, a blowout-proof stem, adjustable stem packing nut, and 100% factory testing, along with its distinctive white handle grip that identifies it as a lead-free model.
Apollo 77FLF-100 Ball Valve
The Apollo 77FLF-100 Series is well suited to potable-water piping because it uses lead-free, dezincification-resistant forged brass wetted components and is certified to NSF/ANSI 61 Section 8, Annex G for drinking-water system components and NSF/ANSI 372 for lead-content compliance. The two-piece valve has a full-port flow path to reduce restriction and pressure loss when fully open, making it a practical manual isolation valve for domestic and commercial water lines.
The Apollo 77FLF-100 series uses female NPT threaded ends, chrome-plated lead-free brass ball, superior RPTFE seats and stem packing, and a quarter-turn lever handle for reliable bubble-tight shutoff. Pressure ratings are 600 psi cold working pressure for 1/4- through 2-inch sizes and 400 psi for 2-1/2- through 4-inch sizes; the valve is rated for 150 psi saturated steam, vacuum service to 29 in. Hg, and temperatures from 0°F to 400°F. Notable durability features include its heavy-pattern forged construction, blowout-proof stem, adjustable stem packing, silicone-free assembly, and 100% factory testing.
DZR Brass: When Standard Lead-Free Isn't Enough
Dezincification is the quiet killer of brass valves. In water with high chloride or low pH, Zinc can selectively leach out of susceptible brass alloys and leaves behind a porous copper skeleton that can crumble under pressure. You'll see white or pinkish deposits and eventual pinhole failure.
Dezincification-resistant (DZR) brass (CW602N and similar alloys) is formulated to resist that attack. If your water report shows chloride above roughly 150 mg/L, soft water with low alkalinity, or a history of brass failures in the building, DZR is cheap insurance against a wall full of replaced valves.
Not sure whether your water chemistry justifies the upgrade to DZR? Talk to a ValveMan engineer at 888-825-8800 and have your water report handy — we'll tell you straight.
Jomar S-100CG DZR Ball Valve
The Jomar S-100CG is a lead-free, DZR brass ball valve suitable for potable-water piping, with NSF/ANSI 61 and 372 certification and wetted surfaces containing less than 0.25% lead. Its DZR brass construction helps resist dezincification in aggressive water, while its two-piece, full-port design minimizes flow restriction and pressure loss.
Designed for soldered copper lines, it includes PTFE seats, a T.E.A.-coated brass ball, a blowout-proof stem, and triple stem sealing with two FKM O-rings and a PTFE seal. Available in 1/2- through 4-inch sizes, the Jomar S-100CG is rated up to 600 WOG, depending on size, and is best used as a manual shutoff valve rather than for backflow prevention or precision throttling.
The Lead Free Check Valve: Backflow Protection for Potable Lines
Lead-free check valves are the simple, automatic safeguard that keeps potable water moving in one direction. Unlike a ball valve, which requires someone to turn a handle, a check valve opens with forward flow and closes when flow stops or reverses, helping protect pumps, water heaters, recirculation loops, meters, and branch lines from reverse flow. For drinking-water service, specify a valve certified to NSF/ANSI/CAN 61 and NSF/ANSI 372.
A check valve provides one-way flow control, but it is not automatically a substitute for a code-required backflow preventer. Where a potable system connects to irrigation, chemicals, process equipment, or another contamination risk, verify local code and specify the appropriate testable backflow-prevention assembly.
Bonomi 100012 LF Check Valve
The 1-inch Bonomi 100012 LF is well suited for potable-water lines because its lead-free brass wetted surfaces meet the 0.25% weighted-average lead threshold and the series is listed to NSF/ANSI 61 and NSF/ANSI 372. This inline, spring-loaded check valve automatically prevents reverse flow, helping protect piping and equipment from unwanted backflow.
It has a 1/2 psi cracking pressure for prompt opening, a flow path designed to reduce head loss, and an NBR soft seat for bubble-tight shutoff at both low and high pressures. The Bonomi 100012 LF check valve uses an AISI 302 stainless-steel spring, is rated 400 WOG in 1/4- through 2-inch sizes (including the 1-inch model), and has a 10°F to 210°F temperature range, making it a practical one-way-flow component for potable-water systems; it is not, however, a substitute for a code-required backflow-prevention assembly.
Red-White Valve 247AB Check Valve
The Red-White Valve 247AB is a lead-free brass swing check valve suited for potable-water piping, with NSF/ANSI/CAN 61 certification for drinking-water contact and NSF/ANSI 372 certification for low lead content. It automatically opens with forward flow and closes when flow reverses, helping protect piping, pumps, and equipment from backflow.
The 1-1/2-inch Red-White Valve 247AB check valve has solder ends for copper tube, a lead-free brass body and disc, PTFE gasket, and a horizontal T-pattern flow path that provides relatively low resistance. It is rated for 200 psi WOG and temperatures to 450°F, although actual system limits depend on the connected copper tube and solder materials. Use it for one-way flow control, not as a substitute for a code-required backflow-prevention assembly.
Gate Valves for Potable Service
Ball valves win most potable jobs on cost and quarter-turn speed, but older designs still have their place. A lead-free DZR brass or bronze gate valve is a solid full-bore isolation valve where you rarely throttle and want minimal pressure drop when fully open. A globe valve, by contrast, is built to throttle because its seat-and-disc geometry gives you fine flow control at the expense of higher pressure drop.
Rule of thumb: gate for on/off isolation, globe for throttling, ball for fast shutoff with low loss. Match the certification requirement regardless of body style: NSF 61 and 372 apply to all of them for drinking water.
Jomar S-301G Gate Valve
The Jomar S-301G is a lead-free, dezincification-resistant brass gate valve designed for potable-water piping, with NSF/ANSI/CAN 61 and NSF/ANSI 372 certification and wetted surfaces containing less than 0.25% lead.
The 1-1/2-inch model has solder ends for copper tube, a handwheel-operated solid wedge, and a non-rising stem that saves clearance where vertical space is limited. Its DZR brass alloy helps resist dezincification in aggressive water, and it is rated for 200 psi water, oil, or gas service. Use the Jomar S-301G gate valve as a fully open or fully closed isolation valve—not for throttling—because the gate and seats can wear if it is left partially open.
Actuation on Potable Lines
Automated potable systems, such as tank fill, booster control, and backflow prevention, may need powered valves. An actuated lead-free brass or stainless ball valve gives you quarter-turn shutoff on a schedule or sensor input. However, do not substitute an actuated shutoff valve for a required backflow-prevention assembly. If you're deciding between an actuated ball valve and a solenoid for a given flow and duty cycle, our comparison of actuated ball valves versus solenoid valves lays out when each one makes sense.
Whatever you automate, the wetted path still has to be NSF 61 and 372 certified. The actuator doesn't touch the water, but the valve body and trim do.
GC Valves NS711GH02C9HJ5 Solenoid Valve
The GC Valves NS711GH02C9HJ5 is an NSF/ANSI 61-G and NSF/ANSI 372-certified solenoid valve for potable-water systems that need electrically controlled on/off flow. Its lead-free brass body and EPDM seal make it suitable for drinking-water contact, while the normally closed, two-way configuration closes automatically when power is removed—providing a fail-closed shutoff for applications such as water treatment, dispensing, automated fill, and control systems.
The GC Valves NS711GH02C9HJ5 1-1/2-inch NPT valve has a full 1-1/2-inch orifice, a pilot-operated diaphragm design, a 120 VAC coil, and a NEMA 4X/IP65 coil enclosure for outdoor and washdown-resistant environmental protection (it is not a submersion rating, though). It is rated for 100% duty cycle and operates from 32°F to 125°F with the listed configuration.
Spec It Right the First Time
The cheapest potable valve is the one you install once. Match the material to your water chemistry, confirm both NSF marks on the submittal, and size the port for the flow you actually need.
