Gemü has introduced its new eSyDrive motorised actuator, designed as a response to increasing requirements in the area of motorised valves as they replace pneumatically operated valves.
Designed on the basis of the hollow shaft principle in conjunction with technology that does not use brushes or sensors, the eSyDrive 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 parametrisation and diagnostics data and the networking of several devices.
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, and depending on the size, the actuator has an actuating speed of between 2mm/s and 6mm/s.
A mechanical position indicator and an electrical status and position indicator are integrated as standard, alongside a manual override.
A suitable emergency power supply module is optionally available, and operators who wish to use the actuator as a control actuator can rely on a design with an integrated positioner or process controller.
Motorized valves are primarily used in areas where the use of compressed air is not desired or possible.
Such condition are found, among others, in large-scale production plants as distribution of compressed air is uneconomical in such facilities, and mobile or decentralised facilities for drinking water treatment.
The Gemü eSyDrive is a linear actuator suitable for open/close and control applications and 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, the 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 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.
