Rosemount R305 & R306 Enhanced Manifolds

Simplify operations, increase safety, and enhance reliability

CHALLENGE

Manifolds serve as a critical mounting mechanism required in many installations and are vital to efficient plant operation because of their ability to shut-off or equalize pressure at the transmitter. However, traditional manifolds can be difficult to operate, present potential safety risks, or degrade over time, leading to sub-optimal performance.

OUR SOLUTION

The Rosemount™ R305 is designed for both differential or gauge pressure applications and assembles directly to any Rosemount Coplanar™ transmitter for a complete solution. The Rosemount R306, designed for in-line pressure transmitters, is suited for gauge or absolute pressure applications.

HOW IT WORKS

•Exclusive Pressure-Lock™ Valve technology offers simplified operation, increased safety, and enhanced reliability.

•Two-piece stem with non-rotating tip provides minimal wear and reduced potential leak paths.

•Enhanced valves offer increased ease of use and improved operator ergonomics through smoother operation.

•Stem and bonnet threads are fully isolated from the process fluid to minimize corrosion.

•When selected with a transmitter, Rosemount R305 and R306 components are fully assembled, high-pressure leak tested at the factory, and arrive ready to install.
