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.
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.
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.
