Back Pressure Regulators
Low, medium and high pressure regulators
Stablize back pressure for your system with a wide range of low, medium or high pressure regulators
When you need to maintain a minimum system back pressure, Graco has the answer. With Graco’s spring loaded, pneumatic diaphragm, or low shear designs; you are sure to find the right BPR to meet your system needs.
Features :
- Stable back pressure for your system
- Lower shear then the standard spring operated BPR
- Local or Remote Operation (PLC)
- Available On/Off Production solenoid kit
- Retrofits on spring operated BPR
- Responsive pressure control for more consistent system pressure
