The Rosemount R305 Integral Manifolds and Rosemount R306 In-line Manifolds have been designed to offer significant user improvements on these basic functions.
The most important improvement for both manifolds is the new Pressure-Lock Valve design which simplifies high-pressure operation, increases safety, and enhances reliability.
Features include:
- Two-piece stem does not rotate in the seat, providing solid closure with minimal wear.
- Easy to turn while delivering positive shut-off.
- Adjustable packing nut simplifies valve maintenance.
- Back seating prevents blowouts for increased user safety.
- Stem and bonnet threads are fully isolated from the process fluid to minimize potential corrosion.
- Modular packing ensures only the stem and body are exposed to the process fluid.
- Larger internal passages to enhance reliability.
- Handles are removable to avoid tampering.
The Rosemount R305 is designed for both differential or gauge pressure applications and mounts directly to any Rosemount Coplanar Transmitter for a complete solution. This reduces the number of potential leak points by 50% compared to traditional bi-planar transmitter setups. 2, 3, and 5-valve configurations are available.
The Rosemount R306 is designed for in-line pressure transmitters for gauge or absolute pressure applications. When a Rosemount R305 or R306 is selected with a transmitter, the components are fully assembled and high-pressure leak tested at the factory. This allows the transmitter to be installed right out of the box, saving time and money.
