Air back-pressure regulator

diaphragmindustrialhigh-precision

Equilibar introduces a new type of back pressure regulator with more than 5X the flow stability of traditional spring regulators. The dome-loaded design precisely matches your process pressure to a pilot set-point signal, even t hrough wide flow rate ranges. The Equilibar® back pressure regulator uses a fully frictionless design that is dramatically more precise than ordinary back pressure regulators - especially in the low and medium pressure ranges. This unique approach also provides much greater support for ultra low pressure applications and very low flow applications. The Equilibar® achieves its precision by providing a fluid set-point pressure to the top of the diaphragm. The Equilibar® offers unmatched performance in very low pressure ranges, with excellent control down to about ½" water column (0.02 psi). It starts 1" water column (0.02 psi). Depending of flow and body size, it can easily achieve precision better than 0.25" water column (0.01 psi).
