GRACO 208997 – Low Pressure Back Pressure Regulator with Gauge, 200 PSI Max, Stainless Steel, 1-1/4″

GRACO 208997 – Back Pressure Regulator, Low Pressure Corrosion Resistant, 200 Max psi, SST, Manual, 1-1/4 (F) x 1-1/4 (F), w/ Gauge, 180 PSI

Low pressure back pressure fluid regulator designed for high flow applications with corrosion-resistant stainless steel construction. Features spring-loaded operation for consistent pressure control with integrated gauge port for monitoring.

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)
