Self-contained instrument for pressure monitoring, valve control

Rotork's Electronic Line Break (ELB) combines pipeline pressure monitoring with intelligent valve control.


Rotork ELB Electronic Line Break combines pipeline pressure monitoring with intelligent valve control. Courtesy: RotorkRotork's Electronic Line Break (ELB) is a robust, self-contained instrument that combines pipeline pressure monitoring with intelligent valve control. It also collects detailed operational data for optimized performance and pipeline safety. The ELB is designed to monitor upstream and downstream pipeline pressure dynamics to provide detection of pipeline breaks and initiate automatic valve actuator movement to an emergency position. Valve actuator control is based on rate-of-drop and rate-of-rise as well as high and low pressure limits.

The ELB provides programmable alarm and alert indications and has up to six remote inputs as well as four configurable solenoid outputs, partial stroke testing and Modbus network connectivity. Environmentally sealed and explosionproof housing can be mounted on the actuator or remotely.
