During a Full Stroke Testing (FST) the Emergency Shutdown (ESD) valve is completely opened or closed during the test. The Full Stroke Test is conducted during planned shutdowns, before installation of the valve system or at Factory Acceptance tests (FAT). In these scenarios it is often a requirement to do a Full Stroke Test as a proof test of the valve system.
Full Stroke Testing validates the entire stroke of the valve and is necessary in order to test if the valve will close fully in case of an emergency shutdown (ESD).
Val Controls provides Intelligent Diagnostic Controllers (IDC24) which can perform Full Stroke Testing, Solenoid Operated Valve Testing and Partial Stroke Testing on all types of valve systems. The testing enables the end-user to collect reliable data of the closing and opening signatures of the ESD valves.
