3003563 - Harris 3520 Series High Flow Pipeline Regulator, 0-250 PSIG

Harris 3520-250 High Flow In-Line Regulator

The Harris 3520-250 is a premium high-flow in-line regulator designed to meet the rigorous demands of industrial gas distribution systems. Engineered by Harris, a global leader in gas control equipment, the 3520 series is specifically built for pipeline and manifold applications where high flow rates and precise pressure control are paramount. Unlike standard cylinder regulators, this unit features 1/2" NPTF inlet and outlet connections, allowing it to be installed directly into facility piping or station drops to step down pressures from bulk systems or high-pressure manifolds.

With a delivery pressure range of 0-250 PSIG, this regulator is versatile enough to support a wide variety of applications, from heavy-duty cutting and heating to supplying assist gas for laser cutting operations. The unit is constructed with a forged brass body and bonnet, ensuring long-lasting durability even in tough industrial environments. A key feature of the 3520 series is its large diameter diaphragm, which provides superior sensitivity and maintains stable delivery pressure even as flow demand fluctuates. This is critical in preventing pressure drops that could compromise process quality.

Safety and longevity are built into the design. The regulator utilizes a one-piece encapsulated seat with an internal filter, protecting the seating surface from particulate contamination often found in piping systems. This design minimizes maintenance downtime and extends the service life of the component. Whether you are outfitting a new fabrication shop or upgrading an existing gas distribution network, the Harris 3520-250 delivers the reliability and performance professionals trust.
