Intelligent controller for pipeline monitoring
The ILB24 product range from Val Controls is a series of Intelligent Line Breakers used for pipeline monitoring and control. The ILB24 provides a straightforward solution to monitor and shut down the pipeline in case of an emergency. The Line Breaker constantly monitors the pipeline pressure and will shut down the flow if abnormal pressure is detected.
The controller offers both minor and major alarms for high and low pressure, rate of drop, rate of rise, and differential pressure. Advanced diagnostic capabilities include 24/7 monitoring and surveillance of the pipeline, event logging, and alarms. Additionally, the product range offers a local control panel option and partial stroke testing.
The range is available with models for both offshore and onshore applications and features an ultra-low power design. It comes with Ex and other relevant certificates from third parties. The controllers are designed to operate in harsh environments and are resistant to high humidity, high and low temperatures, and dusty conditions.
The ILB24 range is compatible with all types of valve systems, including pneumatic and hydraulic applications, spring return and double-acting actuators, making it a versatile solution that easily adapts to your system’s needs.
Product line brochure - ILB24The ILB24 monitors the pressure in pipeline 24/7. The results can be read directly on the unit or from remote by using VCDC.
Major and minor alarms
When configuring the ILB24 a minor and a major pressure threshold are set. If the minor pressure threshold is reached an alarm is displayed on the ILB24 and a message can be sent to the control room. A minor alarm will not trigger any automatic action and it is up to the operator for any onwards actions.
If a major pressure limit is reached the ILB24 can be configured to do an automatic shutdown of the pipeline. It is also possible to only display a major alarm message and not do any automatic actions.
The ILB24 constantly monitors the downstream pressure of the pipeline and can be configured with a high- and low pressure limit. For each limit a major and minor pressure threshold can be set and if those are reached a predetermined action is performed.
The rate of drop is used to determine if a pipeline rupture has occurred. If the pressure drops at a preset rate (measured in bars per minute), a major or minor alarm is triggered, and an automatic shutdown of the pipeline can be conducted.
The rate of rise indicates a sudden increase in pipeline pressure. If the preset major and minor thresholds are reached, a major or minor alarm is triggered, and an automatic shutdown of the pipeline can be conducted.
The differential pressure shows the difference between the upstream and downstream pressure in the pipeline on each side of the valve. A pressure transmitter is placed to monitor the pressure on each side, which calculates
the pressure difference. If the predetermined threshold of the differential pressure is reached, a minor or major alarm is triggered, and an automatic shutdown of the pipeline can be conducted.
Movement alarm detects if the valve has not reached full open or closed within a defined time.
Sensors needed
Each pipeline monitoring feature requires specific sensors to be placed at various points in the valve system.
The list below shows the sensors needed at the upstream pipeline, downstream pipeline, and valve position.

Valve Control
ValConnect is a free software provided by Val Controls which can be used to configure all types of controllers sold by Val Controls. ValConnect is typically used when the controllers are initially set-up.
To configure the controller ValConnect must be downloaded to your PC and the PC connected to the USB-port located on the controllers local user interface.
With ValConnect it is possible to:
• Configure multiple units with the same configuration
• Save configuration for documentation
• Update software on the unit
• Monitor and control all in- and outputs
