Back Pressure Regulators

Control piping pressure upstream of back pressure regulator

Back pressure regulators are designed to maintain system back pressure, ensuring stable fluid flow. Their metal diaphragm or piston mechanism provides precise control of inlet pressure, adapting to various flow and pressure conditions. balance inlet pressure through adjustable spring force, which is set by turning the handle or stem to achieve the desired inlet pressure. Certain models feature a captured vent port, allowing the medium to be safely vented in case of sensing mechanism failure. Back pressure regulators are suitable for gases, liquids, and other media, making them ideal for applications such as analytical instruments, gas delivery systems, chemical processing, and laboratories.
