Back Pressure Regulators

Check out the back pressure regulators at ValveMan–specifically designed to keep an upstream pressure constant and protect your systems against overpressure situations. Our back pressure regulators will open automatically to relieve excess pressure, which allows for safe and effective operation with liquids, gases and steam. Back pressure regulators are used in gas and liquid process control, to protect pumps, and as part of a pressure relief system. We're happy to help you select the correct back pressure regulator model and have many different sizes, materials, and pressure ratings available, or we can help find the exact one for your system!
