Nibco PC1810-LF Circuit Balancing Valve 1 in Press

Product Description

The NIBCO PC1810-LF is a manual circuit balancing valve from the FLO-BOSS MLF series, engineered for hydronic systems where precise flow balance is required. The valve features a brass body with brass and PTFE trim, and EPDM and PTFE sealing components. It is rated for pressures up to 200 psi and temperatures up to 250 degrees F, making it suitable for a wide range of hot and chilled water distribution applications. The 1-inch nominal press-end configuration measures 6.77 inches from inlet to outlet, with a top-to-inlet-center dimension of 4.06 inches. Licensed plumbing professionals and mechanical contractors typically specify and install this valve in commercial and residential hydronic piping systems.

The PC1810-LF is used in hydronic heating and cooling circuits where individual branch flow rates must be set and maintained. Its manual configuration allows the installer to set a fixed flow position during system commissioning. Press-end connections make it compatible with copper tubing systems using standard press tooling, reducing installation time versus threaded or soldered alternatives. Domestic manufacture supports projects with Buy American or domestic-content requirements.
