Engineering Overview of Emerson Pipeline Valves: From Control to System Protection
Emerson Engineering Solutions for Process Control
Emerson Corporation (USA) is a global leader in the development and manufacturing of high-tech automation solutions. EV Group China, as an authorized supplier, offers advanced Emerson products designed to enhance energy efficiency, ensure industrial safety, and provide deep integration with Industrial Internet of Things (IIoT) systems. These technologies guarantee fault-free operation of equipment in the most complex and critical production environments, from oil refining to energy.
Precision Fisher Control Valves
Fisher line control valves are designed for precise control of process flow parameters, ensuring the maintenance of specified pressure, temperature, and flow rate values. The assortment includes ball, segmented, butterfly, and plug valves, allowing for the selection of an optimal solution for any engineering task.
- Application of patented Whisper™ and WhisperTube™ technologies to reduce noise levels and prevent cavitation damage to internal valve components.
- Full integration with Fisher FIELDVUE intelligent digital controllers for predictive diagnostics and automated control.
- Availability of versions for cryogenic media (down to −196 °C) and high-temperature applications (up to 600 °C), as well as for handling aggressive and abrasive flows.
- Compatibility with global digital control protocols, including HART, FOUNDATION Fieldbus, and Profibus, for seamless integration into APCS.

Emerson Overpressure Protection Systems
Safety valves from Crosby, Anderson Greenwood, and Kunkle brands provide reliable protection for vessels and pipelines against exceeding the maximum allowable working pressure (MAWP). The nomenclature includes direct-acting (spring-loaded) and pilot-operated valves, characterized by high accuracy and fast response times.
- Precision setting of set pressure and reseat pressure for gaseous and liquid media.
- Possibility of integration with rupture (safety) discs to create dual protection systems or isolate the valve from aggressive media.
- Wide operating temperature range, allowing the use of valves in cryogenic and high-temperature processes (from −196 to 427 °C).
