GRACO 236770 – Back Pressure Regulator, Stainless Steel, 3/8 NPT(F) x 1/4 NPT(F) Gauge Port, 180 PSI

GRACO 236770 Back Pressure Regulator, Low Pressure Mini, 180 Max psi, SST, 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

Tungsten and carbide materials ensure low wear and long life

Compact and lightweight design saves space and reduces payload for small circulation systems

PTFE/Elastomer hybrid diaphragm withstands wear while maintaining accurate responsiveness

Air operated model available for automated control, Conversion kit (237448)

Compatible Equipment

Paint spray systems

GRACO finishing and fluid handling equipment
