0781-3819 - Victor HSR 2530 Medium Duty Flow Meter Regulator, Nitrogen/Air, CGA 580

Precision Control for Nitrogen and Air Applications

The Victor 0781-3819 HSR 2530-580 is a premium Medium Duty Single Stage Flow Meter Regulator designed specifically for the accurate delivery of Nitrogen and Air. Engineered by Victor, a leader in gas control technology, this unit combines the pressure-reducing capabilities of a regulator with the precise flow measurement of a flow meter into one compact, integrated assembly. It is an essential tool for industrial environments requiring controlled gas atmospheres, such as MIG or TIG welding purging processes, laboratory applications, or specialized pneumatic testing.

Optimized Flow and Pressure Management

This model offers a delivery range of 10 to 60 SCFH (Standard Cubic Feet per Hour), making it versatile for various medium-duty tasks. One of its standout features is the low surge rate design. The regulator is preset at 25 PSIG outlet pressure, which significantly reduces the "gas surge" often experienced when initiating flow. This not only ensures a smoother start to operations but also minimizes gas wastage, providing cost savings over the lifespan of the equipment. The unit is rated for a maximum inlet pressure of 3000 PSIG, accommodating standard high-pressure cylinders with ease.

Robust Construction and Reliability

Built to withstand the rigors of industrial use, the HSR 2530-580 features a forged brass body and housing cap. This material choice ensures superior resistance to corrosion and mechanical damage. Internally, the regulator utilizes a fabric-reinforced neoprene diaphragm and a stem-type seat mechanism, which work together to provide consistent performance and longevity. A bronze sintered filter is integrated into the inlet connection to trap particulates, preventing damage to the seat and ensuring clean gas delivery. Safety is paramount, and this unit includes an external reseating relief valve to protect against over-pressurization.

Ease of Use and Installation

The regulator is equipped with a CGA 580 inlet connection, the standard for Nitrogen and inert gas cylinders, and a 5/8"-18 RH(F) outlet connection compatible with standard gas hoses. The 2-inch high-pressure gauge is clear and easy to read, allowing operators to monitor cylinder contents at a glance. Measuring approximately 7 inches by 4.25 inches by 6.25 inches, its compact footprint makes it ideal for use in tight spaces or on portable cylinder carts without sacrificing performance or durability.
