GRACO 25R487 – Low Shear Fluid Back Pressure Regulator, 300 Max psi, 10 gpm Max flow rate, SST,

GRACO 25R487 – Low Shear Fluid Back Pressure Regulator, 300 Max psi, 10 gpm Max flow rate, SST, Pneumatic, high wear, sanitary Inlet/Outlet, 100 PSI

Low shear back pressure regulator designed to minimize material waste caused by paint shear and maximize service life with Ultralife ceramic coated parts that withstand high wear. Features innovative flow path geometry that provides industry-leading low shear capability, minimizing shear and producing consistent finish quality. Air operated with best-in-class performance in maintaining pressure constant across broad flow rates.

Gracos low shear back pressure regulator (BPR) minimizes shear and prevents paint degradation so that manufacturers produce consistent finish quality.
