GRACO 224486 – Back Pressure Regulator with Gauge, 300 PSI Max, Stainless Steel, 1-1/2″ NPT(F),

GRACO 224486 – Corrosion Resistant Fluid Back Pressure Regulator, 300 Max psi, SST, Acetal & PTFE Wetted Parts, 1-1/4 (F) x 1-1/4 (F), w/ Gauge, 180 PSI

Low shear mechanical back pressure regulator designed for precise fluid pressure control in demanding applications. Features corrosion-resistant construction with SST, acetal, and PTFE wetted parts for compatibility with a wide range of fluids. Ideal for maintaining consistent system pressure in spray finishing, coating, and fluid handling applications.

Features:

Control upstream fluid pressure with Graco back pressure regulators. Our back pressure regulators use closed loop control to maintain the pressure of the system regardless of flow demand. This allows operators to trigger guns, valves, and other flow controls without changing the system pressure.

Stainless steel membrane diaphragm is highly wear resistant while maintaining accurate responsiveness

Low Shear diaphragm valve has minimal restriction to reduce material degradation and color matching issues, especially with metallic paint

Stainless steel wetted materials are compatible with catalyst and waterborne materials

Large fluid passages to accommodate high volume flow rates
