Product Description

Rosemount High Quality 0305 Two-Valve Manifold (Model 0305RC22B11) 

The Rosemount 0305 Two-Valve Manifold (Model 0305RC22B11) is a high-performance flow control solution engineered to ensure reliable operation of pressure transmitters in demanding industrial environments. Constructed from AISI 316/316L stainless steel, this compact manifold combines exceptional durability with precise valve control, making it ideal for applications in oil and gas, chemical processing, power generation, and water/wastewater management. Its robust design, compliance with global safety standards, and seamless integration with Rosemount pressure transmitters position it as a critical component for accurate measurement and process reliability.

Designed for high-pressure systems up to 6000 psi (413 bar), the 0305RC22B11 features a 2-valve configuration comprising an isolation valve and a bleed/vent valve. This setup allows operators to safely isolate the transmitter from the process media while enabling controlled venting or draining during maintenance. The manifold's 1/4" NPT standard port size (with optional 1/2" NPT or BSPP configurations) ensures compatibility with a wide range of piping systems, while its Class VI leakage rating (per ANSI FCI 70-2) guarantees zero leakage, even under extreme thermal cycling or vibration. The use of PTFE or graphite seals enhances sealing integrity, ensuring long-term performance in corrosive or high-temperature environments.

Certified to meet ASME B16.34, API 602, NACE MR0175, ATEX, IECEx, and SIL 2 standards, the manifold is suitable for deployment in hazardous and sour service environments. Its forged stainless steel body provides superior resistance to corrosion, erosion, and mechanical stress, ensuring longevity in offshore platforms, hydraulic fracturing units, and steam systems. The manifold operates efficiently across a broad temperature range (-40°C to 232°C / -40°F to 450°F), adapting to both cryogenic and high-temperature applications.

The 0305RC22B11's modular and rebuildable design simplifies maintenance, allowing replacement of internal components (e.g., valve trim) without full manifold disassembly. Optional accessories such as lockable handles, pressure gauge adapters, and epoxy coatings further enhance safety and durability in harsh conditions.
