Emerson KJ4001X1-BE1 Key features
High-precision positioning: Adopting digital PID control algorithm, combined with real-time feedback from built-in sensors, the positioning accuracy reaches ±0.2% full scale, meeting the needs of fine adjustment.
Intelligent communication and adaptation: Supports two-way communication of HART protocol, and can adjust parameters remotely through handheld terminal or DCS; has adaptive learning function, automatically optimizes response curve, and reduces debugging time.
Flexible configuration: Supports three flow characteristics of linear/equal percentage/fast opening, compatible with various actuators such as pneumatic diaphragm valves and piston valves; optional 4-20mA position feedback module to meet closed-loop control needs.
Typical cooperation cases
Middle East oil and gas field development: Applied to Saudi Aramco's natural gas processing plant, controlling DN150 pneumatic butterfly valves to adjust natural gas flow, accessing the SCADA system through the HART protocol, achieving stable pressure control (error ≤ ±0.3%), and ensuring the safety of downstream pipelines.
European refinery upgrade: In the refinery of Eni in Italy, it replaces the traditional analog positioner to control the DN200 pneumatic gate valve. Its adaptive learning function shortens the commissioning time by 50% and reduces the annual maintenance cost by 20%.
North American power desulfurization system: The flue gas desulfurization system of a coal-fired power plant in Florida, USA, uses KJ4001X1-BE1 to control the limestone slurry pneumatic control valve, and has been running for 3 years without any faults.
Southeast Asian chemical plant: The ethylene distillation tower of an olefin plant in Malaysia is used to control the DN100 pneumatic control valve to adjust the reflux ratio. The IP66 protection level effectively resists the influence of the tropical high humidity and high salt environment, and has been running continuously for 4 years with zero downtime.
