Clean Room

All the products we produce in our cleanroom are manufactured under condition class 10.000. In order to ensure reliable and precise function of our products, numerous functionality tests are carried out already under production and once the devices are finished. Every single valve is carefully calibrated by hand and all data, especially concerning the operating performance, are determined and registered. The products are sterilized with steam in accordance to the standard DIN EN ISO 554.



Our mechanics mount our handcraftet adjustment instruments, that do not need to be sterilized: e.g.: proGAV COMPASSES and proGAV VERIFICATION TOOLS


Our degreed engineers and mechanics produce a large part of individual parts needed for the valve production in-house. Working with the latest CNC-machines allows a precise workflow tailor-made from the drawing up to the complete products.
