Valves are the bosses in the regulatory process

They determine the dynamics of a system and have to withstand even the highest dynamic demands. Therefore, when purchasing such key components, it is important to ensure that they are optimally adapted to the application, the particular medium and the particular environment. This is the only way to achieve a high level of safety, reliability and longevity for your applications and products. As a rule, "off the peg" solutions can not meet the massively increased demands on reliability and stability.

1. Microvalves - General

A microvalve is a particularly small component for regulating or shutting off the flow of gases or fluids. To make this possible, a closure element (e.g. a disc, a ball or a cone) is usually moved almost parallel to the flow direction of a fluid. By pressing the entire closure element onto the appropriate opening, the flow is either reduced or discontinued.
