Optimizing the performance of valve test stands
Valve test stands are special devices that are used to check the functionality and performance of valves. They make it possible to measure various parameters such as pressure, flow rate and tightness and ensure that the valve is working properly. Testing valves is of great importance as they are used in many industrial applications to control the flow of liquids or gases. A faulty valve can lead to leaks, pressure loss or even dangerous situations. Regular testing allows potential defects to be detected and rectified at an early stage to ensure the safety and efficiency of the systems. The use of valve test stands is therefore an important part of quality assurance in the industry.
Valves are manufactured in a wide variety of sizes, materials and designs. Depending on the application and industry, there are special, standard-compliant or standardized testing tasks. Valves are tested during development, production and quality assurance as well as in real-life applications, for example the cyclical function test of quick-closing safety valves on steam turbines. Thanks to an automated testing device and evaluation using ProfiSignal makes testing and evaluation reproducible and significantly reduces the time required for measurement and evaluation. Due to the high flexibility of the Expert Logger and ProfiMessage devices the exact hardware system can be selected for each testing task.
Application highlights of the valve test stands
- Hardware and software from a single source, therefore optimally coordinated
- Data acquisition, control and evaluation with just one system
- Precise determination of closing and opening times using real-time stamps
- Documentation using ready-made reports or automatic export to Word
Practical example of a valve test stand
Fully automated testing of an air release valve test device
A manufacturer of plastic tank systems relies on ProfiMessage devices and ProfiSignal Klicks software to automate a ventilation valve testing device. Five different, fully automated test sequences can be carried out, and a manual operating mode is also available for servicing purposes. The valve test stand is shown here as an overview diagram. Each valve can be switched manually. The test results are determined using ProfiSignal and can be printed out in the form of a report or exported to Excel. Graphics and trends are available as vector-based graphics. The conversion and installation of the ProfiMessage devices and the creation of the entire application, including all tests and test runs, was completed in ten days.
Typical areas of application
of valve test stands
- Testing valves on plastic tank systems in passenger cars
- Cyclical testing of valves on the steam turbine
- Tests accompanying the development of hot water valves
- Testing of flow regulators and flow measurements
