Intelligent control products from Val Controls
Intelligent Diagnostic Controller - IDC24
Intelligent controller for critical valve systems
The IDC24 product range from Val Controls is a series of Intelligent Diagnostic Controllers used for partial and full-stroke testing and monitoring of valve systems. Drawing on decades of experience with valve system testing and monitoring, the IDC24 is the result of this expertise. This gives customers the opportunity to configure the IDC24 to their exact needs. Furthermore, it is designed to be very user-friendly for both manufacturers and end-users in daily use.
The IDC24 offers the opportunity to perform valve diagnostics and predictive maintenance while the system is in use. By conducting PST on the valve while in operation and comparing the performance data from a reference stroke, the current state of the valve can be determined, and the appropriate maintenance can be scheduled.
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 3rd parties and is designed to be used in harsh environments. It is EMC and vibration tested and resistant to high humidity, high and low temperatures, and dusty environments.
The IDC24 range is compatible with all types of valve systems, including pneumatic and hydraulic applications, spring return, and double-acting actuators, as well as 1oo1, 1oo2, 2oo2, and HIPPS systems. It comes with a variety of communication protocols and is designed for integration into Safety Instrumented Systems (SIS), with SIL certification from a 3rd party.
The Flame and explosion proof enclosure made in stainless steel extra-low carbon with an exceptional resistance corrosion against sulfuric, hydrochloric, acetic, formic, and tartaric acids, as well as against acid sulfates and alkaline chlorides. This makes the controller an ideal solution for hazardous environments and places where safety requirements are high.
The controller is equipped with an extension interface which makes it possible to add extra hardware functionality on customer request.
Product line brochure - IDC24Online test and monitoring
Online testing
The purpose of online testing is to monitor and exercise the valves when they are in use. The advantage of Val Control's online testing solution is that the end-user can diagnose the valve while it is in use. Furthermore, the solution provides the possibility of comparing the current performance data with the optimal reference data.
Online Monitoring
Val Controls online monitoring solution offers valve trend analysis, pressure monitoring and valve closing analysis. This data can be compared to previous events helping you to do a root cause analysis of why an unplanned shutdown occurred.

Partial stroke test, PST
When PST is performed the relay will be energized, de-energizing the ESD SOV and moving the actuator to the desired position toward closing. When reached the relay will be de-energized and the ESD SOV will energize and the valve will go back to full open.

Solenoid test, SOT
When SOT is performed the relay will be energized, de-energizing the ESD SOV. As soon as the IDC24 discover a pressure drop in the actuator chamber or a movement of the actuator the relay will be de-energized and ESD SOV energized.
More information about SOV testing
Full stroke test, FST
When FST is performed the relay will be energized, de-energizing the ESD SOV. The valve will go to fully close. When the valve is fully close the relay will be de-energized and the valve will go back to full open.

Emergency shutdown test, EST
EST is not a test performed by the IDC24. If the ESD is de-energized by the control system, the IDC24 will automaticly record the valve going to full close. This can be used instead of a FST for diagnostic.
