Dependent on the device type, either microswitches or proximity switches are used.
They enable reliable end position feedback and can be equipped with a field bus connection upon request (e.g. AS-Interface, DeviceNet etc.).
The latest generation is self-learning.
These devices recognise the valve end positions automatically during initialisation programming.
No time consuming manual setting of microswitches or proximity switches is necessary, retrofitting to installations or recalibration after servicing work becomes considerably easier.
Gemu Australia | Valves, Measurement & Control Systems
GEMÜ is one of the leading manufacturers of valves, measurement and control systems, and is the world market leader of valves for sterile applications in the pharmaceutical and biotechnology industries. This position was achieved following GEMÜ's comprehensive investments in application-specific research and development, amounting to more than 5 per cent of the company's turnover.
The level of innovation is closely linked to location - Germany is regarded globally as a nation of engineers. GEMÜ is over halfway up the chart of the top 1,000 German global market leaders for 2011. The GEMÜ headquarters is in the region that is home to the highest density of global market leaders, the region of Heilbronn-Franken in Baden-Württemberg. GEMÜ's international success is based essentially on the enterprise and pioneering spirit of Fritz Müller, who developed the world's first plastic process valve in 1964. This directly controlled solenoid valve was the starting point for the foundation of GEMÜ that year.
