The Festo LR 157990 Series Pressure Regulator provide constant output pressure with secondary exhausting and primary pressure compensation. Some models also offer a return flow option for exhausting from output to input. Users can secure settings via a latch on the rotary knob, and a lockable version (LRS) is available for additional security.

These units are suitable for use with compressed air (conforming to ISO 8573-1:2010 [7:4:4]) and inert gases. They can operate with or without lubrication, though once used with lubrication, they will always require it.
