As a key actuator, the test solenoid valve 22FDA-F5T plays a vital role in the turbine control and protection system. Especially for extremely demanding steam turbine systems, the response speed and repeatability of solenoid valves have become key indicators to ensure system safety and reliability. Next we will discuss the performance of solenoid valve 22FDA-F5T in steam turbine tests.

22FDA-F5T series solenoid valve is a high-performance plug-in solenoid directional valve known for its compact structure, large flow capacity, low pressure loss and fast response. This kind of solenoid valve is suitable for scenarios that require rapid switching and precise control of fluid media, and is especially suitable for applications in steam turbine control systems.

For steam turbines, the response speed of the solenoid valve is directly related to the system’s ability to respond to emergencies, such as emergency shutdown, load adjustment, etc. Repeatability reflects the solenoid valve’s ability to maintain consistency during multiple opening and closing operations, which is an important indicator of the long-term stability and reliability of the solenoid valve.

Testing of solenoid valve response time needs to follow industry standards and manufacturer’s guidelines. During testing, solenoid valves are exposed to specific environmental conditions, including temperature, pressure, and fluid media. A precision timer is used to record the time from the solenoid valve receiving the action command to completing the state transition. To obtain accurate data, tests are often repeated multiple times to calculate average response times and standard deviations. If the test data falls within the tolerance range specified by the manufacturer, the response speed and repeatability of the solenoid valve are considered to meet the requirements. Any test results outside the specified range may indicate malfunction or degraded performance of the solenoid valve.

Repeatability testing is designed to evaluate the consistency of a solenoid valve operating multiple times under the same conditions. During the test, the solenoid valve needs to perform multiple switching cycles under the same operating parameters, and the action time and state transition accuracy of each time are recorded. The analysis of the data includes calculating the average of all measured values ​​and the difference between the maximum and minimum response times to evaluate the repeatability of the solenoid valve.

For test results that do not meet the standards, the cause needs to be further investigated. It may be that the internal components of the solenoid valve are worn, the solenoid coil is damaged, or there is a problem with the control circuit. If necessary, parts should be replaced or parameters should be adjusted, and then the test should be rerun until the results meet the standards.
