GRACO 237503 - Back Pressure Regulator, Bare, Low Pressure, 180 Max psi, SST, Manual, 3/8 NPT(F) inlet x 1/2 NPT(F) outlet
Low pressure fluid back pressure regulator designed for catalyst and waterborne material applications. Features stainless steel wetted materials for chemical compatibility, tungsten and carbide components for durability, and 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)
