  • With the new, high-performance GEMÜ D40 diaphragm valve, valve manufacturer GEMÜ is launching a new valve type that is geared towards the requirements of the market. The GEMÜ D40 has been equipped with an innovative diaphragm technology and optimized with respect to its design, which enables an increase in performance at plants. This new valve product represents a further step towards the future for GEMÜ. 

     

    The pneumatically operated GEMÜ D40 diaphragm valve is designed for use in sterile applications. The diaphragm hermetically separates the actuator from the working medium. In addition, the GEMÜ D40 particularly impresses with its simple, safe and fast maintenance. The actuator is mounted via a defined union end on block (metal on metal) with only four collar nuts. Likewise, the diaphragm with bayonet pin facilitates installation, while the new diaphragm technology offers greater safety and precision in plants. Due to the new seal system with fixed chambering, the natural setting behaviour of the diaphragm is controlled such that it is no longer necessary to retighten the diaphragm. The optimized rolling behaviour of the diaphragm provides better controllability and ensures low stress on the diaphragm, meaning that maintenance intervals can be adapted to specific applications if necessary. The optimized body design not only saves weight but also ensures a high flow and homogeneous flow characteristics. This enables the GEMÜ D40 to achieve up to 100% higher Kv values. This increase in performance allows smaller valves to be used and therefore enables more compact planning of plants and a high degree of flexibility.  

    The GEMÜ D40 diaphragm valve combines high performance with a state-of-the-art process solution that stands out with its simple operation, compact design and high process efficiency. As a key part of the new, innovative product generation from GEMÜ, it sets new standards in valve designs.

  • With the new GEMÜ C33 HydraLine pressure gauge, GEMÜ – the valves, measurement and control specialist from Ingelfingen – is presenting an innovative solution for the demanding requirements of semiconductor production. As the successor of the tried and tested GEMÜ C32 Hydra-Dry, the new pressure gauge offers an optimized combination of precision, reliability and flexibility. Thanks to its ceramic sensor and an innovative sealing concept, the GEMÜ C33 HydraLine sets new standards in process monitoring. 

     

    With this innovative pressure gauge, GEMÜ is offering an ideal solution for the reliable monitoring of filters, precise back pressure control and the precise measurement of liquid levels. Furthermore, the GEMÜ C33 HydraLine enables high-precision pressure monitoring in numerous process applications.  

    The centrepiece of the GEMÜ C33 HydraLine is its new sealing concept, which is innovative and unique on the market. A ceramic sensor is used here, in which separation of media takes place without transmission fluid as a transfer medium; this is designated as a "dry system". This avoids contamination of the process medium in the event of a leakage. 

     

    The ceramic sensor is also characterized by its high resistance to chemicals, and ensures precise measurement results even under extreme conditions. 

    A key feature of the new sealing concept is the complete envelopment of the sensor and electronic system by a PTFE sensor sheath. This design manages without media wetted O-rings and substantially reduces the number of separation points. Furthermore, the thickness of the diaphragm significantly delays diffusion. 

     

    The new GEMÜ C33 HydraLine pressure gauge will impress you with its compact design, and can be effortlessly integrated into existing systems and plants. The modular design enables space-saving use on valve blocks and facilitates future system expansions. In addition, the fact that compatibility with the predecessor GEMÜ C32 Hydra-Dry has been considered makes the changeover easier for existing customers. 

     

    Two installation versions are available for maximum flexibility: The in-line version allows the sensor to be easily integrated into the piping, without the risk of air cushions that could lead to errors of measurement. With the dead-end version, the sensor can be replaced while the process is running – ideal for plants that are in continuous operation. 

     

    With the GEMÜ C33 HydraLine, GEMÜ is offering a future-proof solution for process monitoring in semiconductor production.
