Product introduction：
The Rosemount R305 Integral Manifold assembles directly to the patented Rosemount Coplanar™ transmitter, eliminating the need for a flange. The Pressure-Lock™ Valve, exclusively featured on the Rosemount R305 and R306 manifolds, offers simplified operation, enhanced reliability and increased operator safety. This lightweight premium manifold is available in 2-, 3- and 5-valve configurations which allows for instrument isolation and controlled venting to ensure measurement integrity.
product feature：
- Exclusive Pressure-Lock™ Valve technology with two-piece stem design offers enhanced reliability, increased operator safety and simplified operation
- Designed for direct assembly to Rosemount Coplanar transmitter interface, eliminating the need for a flange while also reducing overall system weight
- 50% fewer potential leak points than conventional transmitter to flange to manifold interface
- Available in 2-, 3- and 5-valve configurations for MultiVariable, absolute, gage and differential pressure transmitters
- Large internal process bore to resist plugging
- Female NPT process connections
- Provides a leak-checked and pressure tested single point solution when factory assembled to Rosemount pressure transmitters
