Vacuum valve solutions for mass spectrometry or gas analysis are usually tailor-made. Based on selected VAT basic technologies, we develop the optimal solution for the specific application in terms of technical parameters such as conductance, tightness, actuation, degree of outgassing and freedom from particles, temperature resistance and foot print requirements.
