Efficient motorized actuator for globe and diaphragm valves
The new GEMÜ eSyDrive motorized actuator sets new standards in the areas of compact design, speed and accuracy(PresseBox) ( Ingelfingen-Criesbach, )
The development of this new actuator has been based on decades of experience in the area of motorized actuators. GEMÜ already boasts a long-established selection of corresponding products in the areas of linear and quarter turn actuators for globe and diaphragm valves, butterfly valves and ball valves.
Functional principle of the new actuator
Designed on the basis of the hollow shaft principle in conjunction with technology that does not use brushes or sensors, the GEMÜ eSyDrive sets new standards in terms of compact design, reliability and accuracy. The self-locking actuator also offers a high level of reproducibility for positioning and is therefore particularly suitable for use in precise control applications. The Ethernet-based eSy-web interface, in conjunction with an integrated web server, enables the exchange of parametrization and diagnostics data and the networking of several devices.
GEMÜ eSyDrive specifications
After starting initialisation, the actuator automatically adjusts itself to the current process valve, enabling the user to carry out commissioning quickly and easily. If necessary, the user can also make adjustments to the integrated stroke limiter as well as the respective end positions. The power supply for the GEMÜ eSyDrive is ensured via a 24 V DC connection.
Depending on the size, the actuator has an actuating speed of between 2 mm/s and 6 mm/s. A mechanical position indicator and an electrical status and position indicator are integrated as standard. The GEMÜ eSyDrive also features a manual override as standard. A suitable emergency power supply module is optionally available. Customers who wish to use the actuator as a control actuator can rely on a design with an integrated positioner or process controller.
Key applications and availability
Motorized valves are primarily used in areas where the use of compressed air is not desired or possible. Large-scale production plants are cited as examples of such areas, as distribution of compressed air is uneconomical in such facilities. Another example of the areas of use of these valves is mobile or decentralized facilities for drinking water treatment.
The GEMÜ eSyDrive is a linear actuator suitable for open/close and control applications. It can be used both in sterile applications in the pharmaceutical and foodstuff industries and in industrial processes. With its hygienic design and robust construction, featuring a protection class of IP 65, this new actuator is highly versatile.
At launch, the actuator size 2 for diaphragm valves with nominal sizes of between DN 40 and DN 65 and for globe valves with nominal sizes of between DN 32 and DN 100 will be available. The new diaphragm valve will be available under the type GEMÜ 649. The globe valve will be available under the type GEMÜ 549. The product range will be developed successively to cover use in globe and diaphragm valves with a nominal size of between DN 6 and DN 150.
