GRACO 205122 – Mini Back Pressure Regulator with Gauge, 180 PSI Max Inbound, Carbon Steel, 3/8

GRACO 205122 – Back Pressure Regulator, Low Pressure Mini, 180 Max psi, CS, Manual, 3/8 (m) x 3/8 (F), w/ Gauge, Carbon Steel wetted parts

Low Pressure Mini Fluid Back Pressure Regulator designed for catalyst and waterborne coating applications. Features stainless steel wetted materials for chemical compatibility, tungsten and carbide components for durability, and a compact lightweight design ideal for small circulation systems.

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)
