High performance with new diaphragm technology
With the new, high-performance GEMU D40 diaphragm valve has been equipped with a new diaphragm technology and optimised design, which enables an increase in performance at plants.
The pneumatically operated GEMU D40 diaphragm valve is designed for use in sterile applications. The diaphragm hermetically separates the actuator from the working medium. In addition, the GEMU D40 offers 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 optimised 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 optimised body design not only saves weight but also ensures a high flow and homogeneous flow characteristics. This enables the GEMU 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.
With the launch of the new product generation, GEMU is taking a step into the future. 'LEAP into the future', with its abbreviation for "Lean. Effective. Agile. Platformized.", embodies both progressive products in a modular design and innovative production methods.
The products of the GEMU LEAP product generation not only include the GEMU D40, but also two further valves and an add-on component:
GEMU S40 - the pneumatic globe valve with angle seat and straight seat designs
GEMU P40 - the efficient tank bottom valve with PD design
GEMU 12A0 - the intelligent electrical position indicator
The new valves have actuator modules on a uniform platform architecture to enable flexible adaptation to different requirements. The GEMU 12A0 electrical position indicator is characterised by modern communication interfaces and an integrated sensor system. It is compatible with the valve types from the new product generation and offers a space-saving and simple automation option.
