Different vacuum valves available to cover the wide range of possible applications in industry and research. The excellent tightness of a vacuum valve is essential, and that is exactly what these valves offer—along with a long service life, low maintenance requirements, and short opening and closing times. Electropneumatic or electromagnetic vacuum valves are excellently suited for systems requiring an automated process flow. Easy operation of the vacuum valve plays also plays a crucial role in the decision process.
