Electrically operated solenoid valve
Valve specialist GEMÜ is introducing the new GEMÜ J70 electrically operated 2/2-way solenoid valve, optimising its existing solenoid valve product group.
The GEMÜ J70 electrically operated solenoid valve is suitable for applications with low flow rates in analysis, vacuum and dosing technology and enables precise dosing. The resistant plug diaphragm made of PTFE (TFM) has a unique sealing concept. PD technology provides for a high degree of accuracy for customer-specific applications.
With the PD (plug diaphragm) technology, the media wetted area is separated from the actuator by a plug diaphragm made from modified PTFE. PTFE is composed of linear carbon chains which are surrounded by fluorine atoms. They spatially shield the carbon atoms and protect the molecule from chemical attack – even at higher temperatures.
The compact GEMÜ J70 solenoid valve features a space-saving design and impressive features such as low wear and simple wear part replacement alongside good cleanability. The coil can be replaced without removing the valve body from the piping.
With CONEXO and an RFID chip, the GEMÜ J70 solenoid valve can be clearly identified, enabling efficient documentation of maintenance. In addition, the solenoid valve is variable and extendable and suitable for valve manifolds and multi-port valve blocks.

Globe valves are granted USP Class VI certification
The Gemü globe valves 507, 550 and 554 with stainless steel valve bodies and PTFE seals from the valve specialist Gemü have been awarded approval in accordance with USP Class VI. They now comply with the prerequisites for application in the medical and pharmaceutical industries.
The U.S. Food and Drug Administration (FDA) divides the plastics used in the medical and pharmaceutical industries into six biocompatibility classes in the American Drugs and Medicines Register (USP). The most stringent of the six categories is the USP Class VI classification. It is the prerequisite for use of the materials in the medical and pharmaceutical industries.
With immediate effect, the Gemü globe valves 507, 550 and 554 with PTFE gland packing (Gemü code 5P) and stainless steel valve bodies (Gemü code 37, 34 or C2) now have certification in accordance with USP Class VI and are therefore approved for use in the medical and pharmaceutical industries.

New Profinet fieldbus interface
Tried and tested and versatile
Gemü is now expanding its tried and tested Gemü 1436 cPos positioner to include additional options in fieldbus environments. With the new Profinet fieldbus interface, the Gemü 1436 cPos positioner achieves a transmission rate up to 8 x higher. However, the option to perform all setting options easily via the fieldbus interface instead of having to enter these locally on the operating unit remains unchanged. In this way, the process data for controlling the valve position is also transmitted digitally. The new fieldbus type with Profinet also offers other practical benefits for the user, such as a more stable connection and additional configuration options.
In addition to the “standard” versions with analogue signals (0/4…20 mA) and the already available DeviceNet versions and Profibus DP, the electro-pneumatic positioner is now also available with Profinet, the industrial Ethernet standard, which will increasingly become the established standard in the near future in the automation sector.
Gemü is therefore expanding its product range in the area of positioners for pneumatically operated equipment. To achieve the widest range of control tasks, the valve specialist now offers a complete product range of positioners. In doing so, the individual series each have specific features and characteristics whereby a balance must always be struck between wide-ranging functionality and cost/benefits.
