GRACO 903508 – Back Pressure Regulator, Low Pressure Corrosion Resistant, 15 GPM, 180 Max PSI,

GRACO 903508 Back Pressure Regulator, Low Pressure Corrosion Resistant, 15 GPM (56.7 lpm), 180 Max psi, Manual, 3/8 (m) x 3/8 (f), with Gauge

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 wetted materials are compatible with catalyst and waterborne materials

Hardened stainless steel seat ensure low wear and long life

PTFE/Elastomer hybrid diaphragm withstands wear while maintaining accurate responsiveness

Large orifice accommodates high volume flow rates

Air operated models available for automated control, Conversion kit (15J498)
