Product description

Product description GEMÜ CONEXO The interaction of valve components that are equipped with RFID chips and an associated IT infrastructure actively increase process reliability. Thanks to serialization, every valve and every relevant valve component such as the body, actuator or diaphragm, and even automation components, can be clearly traced and read using the CONEXO pen RFID reader. The CONEXO app, which can be installed on mobile devices, not only facilitates and improves the "installation qualification" process, but also makes the maintenance process much more transparent and easier to document....

1) Surface finishes of customized valve bodies may be limited in special cases. 2) Or any other finishing method that meets the Ra value (acc. to ASME BPE). 3) The smallest possible Ra finish for pipe connections with an internal pipe diameter < 6 mm is 0.38 |jm. 4) When using these surfaces, the bodies are marked according to the specifications of ASME BPE. The surfaces are only available for valve bodies which are made of materials (e.g. GEMU material codes 40, 41, F4, 44)) and use connections (e.g. GEMU connection codes 59, 80, 88) according to ASME BPE. 5) Not possible for GEMU connection...

Technical data Working medium: Corrosive, inert, gaseous and liquid media which have no negative impact on the physical and chemical properties of the body and diaphragm material. The valve will seal in both flow directions up to full operating pressure (gauge pressure). For special oxygen version (code S): only gaseous oxygen Media temperature: Temperature development at the proximity switch depending on the media temperature Data at room temperature

Technical data * The service life of the diaphragms is reduced at temperatures below -10 °C and above +100 °C. The maintenance cycles must be carried out in shorter time intervals accordingly.
