How does a back pressure valve work

WebApr 17, 2024 · Back pressure (or backpressure) is a resistance or force opposing the desired flow of fluid through pipes, leading to friction loss and pressure drop. The fluid is what is directed, tending to flow away from high-pressure regions and toward low-pressure regions. 13 Back Pressure Valve Watch on What are examples of non functional requirements? WebDec 4, 2024 · The back pressure is generated by the metering section of the mixing screw. It is possible to control the hydraulic back pressure during the injection molding process. The back pressure settings typically start at fifty PSI and increase in ten PSI increments. The maximum hydraulic pressure for the equipment is normally 300 PSI.
