This is a mechanical back pressure regulator in the P200-RM model line. Based on the model designation key, this appears to be a pressure regulation valve with back-pressure regulation action. Models 233771, 233772, 234268 and 234269 are mechanically operated back pressure regulators that limit the supply pressure to a set value by opening an outlet and guiding back excess material when the predetermined pressure has been achieved. These valves are used in circulating systems. Part 233772 is one of four Mechanical Back Pressure Regulator part numbers shown in this exploded view diagram. The diagram shows the complete assembly with numbered components 1-27, but no specific specifications are provided on this page for individual part numbers.
