Graco Incorporated 236770 Back Pressure Regulator

Graco Incorporated 236770 Back Pressure Regulator is a pressure-regulating component identified by part number 236770. It is rated for a maximum working pressure of 180 PSI (21 BAR / 2.1 MPa). This back pressure regulator is designed to maintain stable pressure in fluid lines by venting excess flow when downstream pressure rises, helping to protect components and maintain consistent performance in connected systems. The device is listed with three common pressure units—180 PSI, 21 BAR, and 2.1 MPa—to aid cross-reference with existing system specifications and schematics. As part of Graco's regulator family, the 236770 is the official model designation used for this back pressure regulator, allowing technicians and purchasers to identify and source the exact replacement or spare part without ambiguity.
