GEMÜ engineers and technicians factor sustainability criteria into the development, design and production process as far as possible. This enables a variety of different advantages to be implemented:
- Material savings: On the product itself and/or on plant design for our customers
- Energy savings: During manufacturing and/or during use
- Environmentally friendly materials: During manufacturing and/or during use
- Transport savings: On the product and/or on the finished plant
With GEMÜ 550 and GEMÜ 650, the employees of the GEMÜ Dome Development and Innovation Centre have designed two extremely thin-walled stainless steel valves and made them marketable. As well as conserving important raw materials, this also allows the valves to be installed at closer intervals. This enables a further saving to be achieved in terms of space requirements. The redesign of the GEMÜ 690 diaphragm valve is another example. It was optimized in several ways, enabling a reduction in size, material savings of up to 50% and a significantly reduced control air consumption to be implemented. The most recent innovative product also takes this concept into account: The body of the GEMÜ 553 distribution valve is joined and sealed without any further fittings, pipes or additional weld seams.
Control air consumption is an important subject not only for pneumatic valves, but also for automation components that are powered using it. To this end, the GEMÜ 4242 combi switchbox offers a combination of electrical position indicator and a 3/2-way pilot valve. Using this product in place of a position indicator in conjunction with external pilot valves significantly reduces compressed air consumption, for example, and thereby enables the plant to be operated with reduced costs and lower resource consumption. The motorized actuators that have been part of the GEMÜ product range for many years also make a significantly better “footprint” possible for plant operation, because they only consume energy when they carry out an action, whereas compressed air must be continuously available for pneumatic valves.
As part of product optimization and innovations, the design and testing departments continuously examine options for using more environmentally friendly materials and replacing more questionable materials. For instance, the variable area flowmeters have been designed using substitute materials for several years, allowing them to contain the absolute minimum amount of lead required for them to (continue to) function.
The M blocks, made of plastic or metal, are a further example of GREEN ENGINEERING. These compact valve block systems incorporate a wide variety of components into a customized and tested unit. As a result, fittings, welds and solvent cemented joints are kept to a minimum. Not only does this increase the plant reliability and reduce the installation times, but it also simplifies shipping and reduces space requirement for inventory and plant engineering. In addition, unnecessary material is removed, which reduces the heating time of components during sterilisation processes, for example.
