Graco | 903508 Back Pressure Regulator, Low Pressure Corrosion Resistant, 15 GPM (56.7 lpm), 180 Max psi, Manual, 3/8 (m) x 3/8 (f), with Gauge
Graco
Model: 903508
Back pressure regulators utilize closed-loop control to maintain system pressure, irrespective of flow demand.
- Stainless steel wetted components offer compatibility with catalyst and waterborne materials.
- A hardened stainless steel seat ensures minimal wear and extended operational life.
- The PTFE/Elastomer hybrid diaphragm provides wear resistance while maintaining precise responsiveness.
- A large orifice design accommodates high-volume flow rates.
- Air-operated models are available for automated control; conversion kit (15J498) is sold separately.
