The U3L0 offers the smallest port connection of the “Ultra Low-flow” UL series. These smaller ports are ideal for applications where minimal dead volume is required.
The U3L1 is the most popular model in the entire UL “Ultra Low-flow” series of back pressure regulator. The 1/8 port size is ideal for catalyst or research sized applications in a laboratory scale environment. The U3L1 is most often used to control reactor vessel pressures between 1000 and 3000psi, but with optional membrane diaphragm materials can accurately control at pressures near atmosphere.
The U3L2 offers the largest port connection size for the U3L series. The 1/4 inch ports are ideal for systems that utilize larger tubing sizes. Even with these larger ports the U3L still maintains its superior pressure control at low flow rates while operating up to 3000 psi / 200 Bar.

Equilibar’s Research Series is designed to meet the demanding requirements catalyst research and high pressure reactor control applications. All our Research products hold stable pressure across very wide flow ranges, and can handle liquids, gases, or multi-phase mixtures. These products are commonly used with highly aggressive chemicals, and can perform at temperatures up to 450C.
Equilibar Research Series units are 1:1 dome-loaded, meaning that a pilot pressure must be supplied to the dome of the BPR equal to the desired set-point. This pilot pressure can be supplied by a manual gas regulator, or by an electronic pressure regulator for computer automation.
The UL series uses a single outlet orifice design. Your application engineer may recommend the UL Series in certain ultra-low flow applications.
