Generant states that BPRX regulators sense pressure at the inlet and begin opening when inlet pressure exceeds the regulator setpoint. 

The Generant BPRX Series is designed specifically for use as a high-efficiency economizer/back pressure regulator on large cryogenic tanks, trailers and systems. Its optimized diaphragm and adjustment-spring design provides high flow when pressure rises above the desired setpoint.

Applications may include:

Cryogenic storage tanks, cryogenic trailers, industrial gas systems, pressure-limiting systems, economizer circuits and related industrial gas equipment.

Important: Please confirm compatibility, pressure requirements, media and installation requirements before purchasing. Professional installation is recommended for pressure and cryogenic systems.

Generant warns that oxygen-service cleanliness can be compromised after the factory-sealed packaging is opened, so do not advertise an opened unit as maintaining factory oxygen-clean status unless you can verify its handling/packaging.
