Bonomi 100712LF series sweat-end lead-free brass check valves feature a spring-loaded soft seat for fast action and bubble-tight shutoff at both high and low pressures. They install without special handling or high-temperature solders because the valve bodies are made without lead-substitute additives such as bismuth or silicon. The Bonomi 100712LF features a forged lead-free brass body that is stronger and lighter than sand-cast valve bodies with zero porosity. All brass components are made from brass alloy CW510L/ASTM C28500.
