Rosemount R306 Enhanced In-Line Manifold

The Rosemount R306 Enhanced In-Line Manifold is engineered to provide improved safety and performance compared to conventional inline manifolds. It incorporates advanced valve designs such as the Pressure-Lock™ system with a two-piece stem, which enhances sealing integrity, prevents stem blowout, and ensures smooth operation under high-pressure conditions. The inline configuration allows direct installation between the process and measurement device, reducing the number of fittings and minimizing potential leak points. Available in block-and-bleed configurations, it enables efficient isolation and venting for maintenance, calibration, and system protection. Its compact design also simplifies installation in space-constrained environments while maintaining high reliability.

In addition, the manifold is constructed from durable 316/316L stainless steel and optional alloy materials, offering excellent resistance to corrosion, high pressure, and temperature extremes. It supports flexible mounting with standard 1/2–14 NPT connections and is suitable for both horizontal and vertical installations. The large internal bore design helps prevent clogging in dirty or viscous process media, while factory assembly and testing ensure leak-free operation from the start. With enhanced safety features, rugged build quality, and reliable performance, the R306 is well-suited for critical industrial pressure measurement systems.
