Consolidated - Extending Pressure Relief Protection up to 1020°F

Consolidated 2900 Series High Temperature Pilot-Operated Safety Relief Valve (POSRV)

As industrial processes continue to push operating temperatures higher, manufacturers require pressure relief solutions that can deliver exceptional reliability, tight sealing performance, and regulatory compliance under increasingly demanding conditions. To meet this challenge, Baker Hughes has expanded its proven Consolidated™ 2900 Series pilot-operated safety relief valve portfolio with the introduction of the 2900 Series High Temperature (HT) configuration, extending application capability up to 1020°F (550°C).

Built on the trusted 2900 Series platform, the new HT version has been specifically engineered for severe temperature services where conventional soft-good limitations can impact long-term valve performance. Through targeted enhancements to both the pilot and main valve assemblies, the 2900 HT delivers reliable operation while maintaining the leak-tight characteristics expected from a pilot-operated relief valve.

Key innovations include high-temperature PTFE sealing materials within the pilot, a micro-drilled pilot piston designed to optimize venting response, and carefully selected high-temperature metallic components. For selected D through J orifice sizes, the main valve incorporates an extended cover plate and split piston arrangement that increases the thermal separation between the process media and critical sealing elements while accommodating thermal expansion.

Behind the new high-temperature capability is an extensive engineering and validation program. Development included thermal modelling, heat-transfer evaluations, finite element analysis, and multiple phases of high-temperature testing. Successful operation was demonstrated at inlet temperatures approaching 1000°F, validating performance at temperatures close to the product's maximum rating.

The result is a pressure relief solution capable of extending the previous temperature limit of 850°F to 1020°F, opening new possibilities for steam, gas, and other high-temperature applications across power generation, refining, petrochemical, and industrial process facilities. Available in orifice sizes D through T and inlet connections from one inch to eight inches, the valve provides broad application flexibility while leveraging the field-proven reliability of the Consolidated 2900 Series platform.

By combining innovative thermal management design with the proven advantages of pilot-operated technology, the Consolidated 2900 Series HT POSRV provides operators with a premium alternative to traditional spring-loaded safety relief valves, helping reduce leakage, improve process efficiency, protect critical assets, and support safe plant operation in demanding high-temperature environments.
