591X-750 - Gentec 591X Series High Pressure Oxygen Regulator, 0-750 PSI

Heavy-Duty Piston Regulator for High Pressure Oxygen Applications

The Gentec 591X series regulator is engineered for professionals requiring substantial delivery pressures that standard diaphragm regulators cannot reliably sustain. Specifically configured for Oxygen service with a CGA 540 inlet, this unit provides a robust delivery range of 0 to 750 PSIG. The core of its performance lies in its piston-type actuation mechanism. Unlike rubber diaphragms which can be sensitive to pressure spikes and wear over time under high loads, the piston design utilizes solid brass components to manage airflow, ensuring consistent output even at the upper limits of its pressure range.

Constructed with a forged brass body and housing cap, this regulator is built to withstand the physical demands of industrial environments, from shipyards to fabrication shops. The internal architecture includes a sintered bronze inlet filter, a critical feature that prevents dust, dirt, and tank scale from entering the regulator seat, thereby extending the service life of the unit and maintaining precision. The 2.5-inch gauges are dual-scale, providing clear readings for both cylinder contents and delivery pressure, allowing operators to monitor system status at a glance.

This model is particularly suited for applications such as high-pressure vessel testing, heavy-duty cutting systems, and pressurization tasks where safety and reliability are paramount. The 591X series also incorporates an internal relief valve, adding a layer of safety by preventing over-pressurization. When your operation demands more than the standard 100-150 PSI delivery, this 750 PSI capable unit offers the power and control necessary to get the job done efficiently.
