Our oxygen regulators are constant-pressure calibrated to deliver about 15 psig. (1 bar) of pressure dynamically (that is while flowing). They have been designed to stop the high-pressure inlet side while the low-pressure outlet side is stopped (static no-flow condition) at a pressure of about 20 psig. This allows for a semi remote on/off control action of the regulator. This is utilized in the EDS, XCR on/off control system and in the XCP systems while no stations are connected to any of the outlets. Rated for inlet pressures up to 3,000 psi (207 bar).
Looking for a 2-Port Regulator? When we designed these regulators it would cost as much to manufacture a 2-port version as the 4-port. As these are very compact we decided to only manufacture the 4-port version, thus giving the user the option to expand in the future if needed. All ports are self sealing when not in use.
