The PRDB-18MM-A-B-C is a microminiature 18-mm-diameter single-stage diaphragm pressure regulator for situations where space or weight optimization is critical.
The device has two inlet and two outlet ports so lines can connect in four different configurations and provides the option of connecting a pressure gage directly to the pressure regulator. The regulator controls output pressures from 0 to 20 psig and is targeted for low-pressure regulation, even below 1 psig. Maximum rated inlet supply pressure is 300 psig.
