0781-3558 - Victor VTS252A-350 Two-Stage Methane/Hydrogen Regulator CGA 350

Heavy-Duty Two-Stage Regulator for Methane & Hydrogen

When your operation demands unwavering pressure stability for Methane or Hydrogen gases, the Victor VTS252A-350 (0781-3558) stands out as a top-tier choice. This medium-duty, two-stage regulator is built to deliver consistent performance in environments where a change in delivery pressure could negatively impact test results or process performance. By stepping down the high-pressure gas in two stages, the VTS252A-350 eliminates the "decay" often seen in single-stage regulators, providing a steady 2-15 PSIG output from a full cylinder down to an empty one.

Victor has constructed this unit with the professional user in mind. The body is crafted from die-forged brass, offering superior strength compared to cast alternatives. The spring housing cap is also die-forged brass, ensuring the entire assembly can withstand the physical demands of a busy shop or industrial site. The regulator features large, easy-to-read 2-inch steel gauges—one measuring the inlet pressure up to 4000 PSIG and the other monitoring the low-pressure delivery up to 30 PSIG. This allows operators to monitor system status at a glance.

Maintenance and longevity are key features of the VTS 250 series. The stem-type seat mechanism aids in positive sealing, while the sintered bronze inlet filter traps debris before it can damage the seat. For precise adjustments, the regulator utilizes a high-quality adjusting spring and a friction-reducing Delrin bushing. Whether you are setting up a fuel gas supply for specialized heating applications or managing hydrogen for industrial processes, the VTS252A-350 provides the accuracy and ruggedness associated with the Victor brand. It connects via a standard CGA 350 inlet and offers a 9/16"-18 LH(M) outlet for compatibility with standard hoses and fittings.
