OVERVIEW

Product Overview

The Victor 0781-4254 GT350-150-320 is a premium heavy-duty two-stage regulator designed specifically for Carbon Dioxide (CO2) service. Part of the renowned GT350 series, this regulator is engineered to provide precise and constant delivery pressure, making it an essential component for industrial, laboratory, and testing applications where pressure stability is critical. The two-stage mechanism effectively compensates for the decay in cylinder pressure, ensuring that the output remains steady without the need for frequent manual adjustments.

Technical Engineering

Built to withstand harsh industrial environments, the GT350-150-320 features a robust forged brass body and housing cap. The internal design utilizes a stem-type seat mechanism which offers reliable sealing and longevity. A key feature of this model is the Delrin cap bushing, which provides smooth and precise pressure adjustment, allowing operators to fine-tune settings with ease. The regulator is equipped with 2-inch gauges that are easy to read, displaying both inlet cylinder pressure and delivery pressure. Safety is paramount, and this unit includes an external self-reseating relief valve (not designed to protect downstream equipment, but to protect the regulator itself).

Performance Specifications

This model is rated for a maximum inlet pressure of 3000 PSIG and offers a delivery pressure range of 5 to 150 PSIG. It connects via a standard CGA 320 fitting, which is the industry standard for Carbon Dioxide cylinders. The inlet assembly includes a sintered bronze filter to trap particulate matter, protecting the internal seat from damage and extending the service life of the regulator. Whether used for shielding gas distribution, beverage carbonation systems, or industrial process control, the Victor GT350 series delivers consistent performance.

Applications

The Victor GT350-150-320 is suitable for a wide range of heavy-duty applications. It is frequently utilized in:

  • Industrial fabrication and welding
  • Chemical and petrochemical processing
  • Laboratory research and testing
  • Purging and pressurization systems

FAQ

A two-stage regulator reduces cylinder pressure in two steps, which keeps the delivery pressure constant even as the cylinder pressure drops. A single-stage regulator may show a slight increase in delivery pressure as the cylinder empties.

This regulator is designed specifically for Carbon Dioxide (CO2).

It has a CGA 320 inlet connection, which is the standard fitting for CO2 cylinders.

The maximum delivery pressure for this model is 150 PSIG.

Yes, CGA 320 connections typically require a flat washer (nylon or fiber) to ensure a proper seal between the regulator and the cylinder valve.

No, this regulator has a CGA 320 fitting. Argon and Nitrogen cylinders typically use CGA 580 fittings. You should use a regulator designed for the specific gas service.

The maximum inlet pressure is 3000 PSIG.

Yes, the GT350 series is a heavy-duty line designed for demanding industrial environments.
