Shafer Automatic Line Break
The Shafer™ Automatic Line Break System by Emerson provides rapid, automatic valve shutdown in response to abnormal pressure changes, ensuring pipeline safety and environmental protection.
The Shafer™ Automatic Line Break System, developed by Emerson, is a safety-critical monitoring and shutdown device designed to detect and respond automatically to abnormal pressure conditions in pipeline systems. This system provides rapid, automatic valve closure in the event of a line rupture, pressure drop, or surge, ensuring pipeline integrity, personnel safety, and environmental protection.
Engineered for integration with Shafer gas-over-oil or hydraulic actuators, the Automatic Line Break (ALB) System continuously monitors pipeline pressure and activates the actuator’s shutdown mechanism when a preset threshold is reached. This automatic response minimizes product loss and prevents potential hazards associated with pipeline failure.
The Shafer ALB System is built with robust, field-proven components for long-term performance in onshore and offshore pipeline environments, and is widely used in oil and gas transmission, distribution, and storage facilities. Its modular, adjustable design allows easy calibration, testing, and maintenance without interrupting system operation.
