0781-3656 - Victor HRF2435P-580 Argon/CO2 Flowmeter Regulator CGA 580

Victor HRF2435P-580 Pro Series Flowmeter Regulator Overview

The Victor HRF2435P-580 (SKU: 0781-3656) is a high-performance medium-duty regulator/flowmeter combination designed specifically for the precise control of inert gas shielding in MIG and TIG welding applications. Part of the renowned HRF 2400 Pro Series, this unit integrates a traditional pressure regulator with a high-accuracy flowmeter, providing a streamlined solution for industrial gas management. The device is calibrated for both Argon and Argon/CO2 mixtures, making it a versatile choice for fabrication shops handling diverse welding processes.

Engineered for durability and longevity, the HRF2435P features a robust machined brass body paired with a die-cast zinc-alloy housing cap. This construction ensures resilience against the physical demands of industrial environments while maintaining the precision required for high-quality welding. The internal mechanism utilizes a fabric-reinforced neoprene diaphragm, which offers superior sensitivity and response compared to standard elastomer diaphragms. This design allows for accurate pressure regulation and flow control, even as the cylinder pressure fluctuates or drops during extended use.

A standout feature of the Pro Series is the redesigned flow tube and float assembly. The tube is rotatable and features enlarged, bold graphics that significantly improve scale visibility from a distance. This enhancement reduces operator error and allows for quick visual checks of gas flow rates. The unit delivers a flow range of 0-70 CFH, supporting high-flow applications often required in heavy structural fabrication. Flow control is managed via a precision needle valve that ensures accurate delivery, maintaining stability even when flow rates exceed 50 CFH.

Safety and compliance are paramount in the design of the HRF2435P-580. The regulator includes an external self-reseating pressure relief valve (PRV) to protect the unit from over-pressurization, although it is not designed to protect downstream equipment. Additionally, a safety over-pressure burst mechanism is built directly into the flow tube for added operator protection. The inlet is equipped with a sintered bronze filter to prevent particulate contamination from entering the regulator seat. The unit is third-party ETL listed to UL Standard 252 and comes with a two-year limited warranty, reflecting Victor's commitment to quality and reliability.
