The Equilibar® U3L back pressure regulator is part of the ultra low flow series. Therefore customers use this unit in applications where you require ultra-low flow. It is able to hold pressure with only a fraction of a milliliter per minute. The minimum Cv value is 1·E-09 to 0.05 with only one model. The unit can withstand 206 bar (3000 PSI) gauge. With polymeric diaphragms like glass reinforced PTFE or PEEK the low flow performance is unsurpassed. Depending on the chosen diaphragm material and seals, you can use the units up to 300°C.
Next, to this type in the ultra-low flow series, we also offer the U6L units, that can withstand 412 barg (6000 PSI) and the U10L units that can withstand 690 barg (10.000 PSI).
