Brass Swing Check Valves are designed to automatically block backflow in household and commercial piping systems. Commonly installed in cold and hot water supply lines, they help ensure one-way flow, prevent contamination, and protect water meters, pumps, and storage tanks from reverse pressure.
Made from premium-grade brass, this valve features a threaded connection and internal swing disc, which opens with forward flow and closes when flow stops or reverses—without the need for manual operation. It is ideal for use in residential plumbing, booster pump systems, solar water heating, and building water inlet systems.
Available in common sizes 1/2" ~ 4". BOTE’s brass swing check valves meet CE and ISO9001 certifications to guarantee quality, performance, and global compatibility.
We support OEM & ODM customization, including logo engraving, surface treatment, special thread standards (BSP/NPT), and packaging design to meet your specific market requirements.
