New manifold valve design for pressure transmitters
Manifolds shut off or equalize pressure at the transmitter and provide the critical mounting mechanisms required in many installations. The Rosemount R305 Integral Manifolds and Rosemount R306 In-line Manifolds (photo) 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. New 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.
