Pneumatic applications have been using piezo technology for several years as its functionality offers numerous advantages. This means that it not only provides fast and precise pressure and flow control, but also has low particle emissions as well as quiet operation. Additionally, piezo technology produces very little heat because no more energy is needed when the valve is opened as much as it needs. Therefore, the use of piezo valves is especially suitable in areas where heat must be prevented. Since piezo-driven products generally consume low energy and have a compact design, high packaging density can be achieved. For this reason, piezo valves are often used in multi-purpose solutions.
