The XCP-FPR regulators (CGA-540 or DIN-477) are available with a high pressure cylinder monitoring gauge.
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.
