A Better Alternative:  Piezo Technology In Pneumatic Valves

Piezo valves are often a better alternative to conventional solenoid valves, especially in the areas of flow and pressure control and as directly controlled proportional valves. They are small, lightweight, extremely precise, very durable, incredibly fast and above all they save energy. For example, piezo valves do not need any energy to maintain a switching status. They therefore generate virtually no heat. In ATEX applications, many piezo valves are classified as intrinsically safe. What is more, piezo valves can potentially be operated without any noise. Another key advantage is that they always work proportionally – and are very wear-resistant too.
