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.
