Precision pressure regulators LRP, LRPS
The precision pressure regulators LRP and LRPS are suitable for sensitive applications that require a hysteresis of 0.02 bar. The output pressure p2 is adjustable within the pressure regulation range.
These regulators allow the precise pressure to be set when used statically as well as dynamically. Operating pressure fluctuations are almost entirely compensated. They are characterised by a good response in the event of rapid changes to the operating pressure and flow rate.
They are available in sizes 40 mm with a 1/8″ connecting thread and 300 l/min standard nominal flow rate as well as 50 mm with a ¼” connecting thread and 2,300 l/min standard nominal flow rate.

Regulators, individual devices
The precision pressure regulators of the LRP series guarantee a precise pressure setting. Fluctuations of the input pressure are almost entirely compensated by the LRP. In addition, they offer a good response to rapid changes of the input pressure and flow rate.
They are available in two sizes for the most common standard applications.
