GRACO 25T477 - Medium Pressure Fluid Back Pressure Regulator, 2000 Max psi, 5 gpm Max flow rate, SST, Pneumatic, 3000 PSI, 3/8" NPT
Medium pressure pneumatic back pressure regulator that maintains upstream fluid pressure regardless of flow demand, allowing operators to trigger guns, valves and other flow controls without affecting system pressure. Provides consistent fluid control crucial for guaranteeing quality from finishing processes with better resolution than other brands for more accurate pressure control.
Improve finishing process control with this medium pressure, pneumatic back pressure regulator (BPR).
