Product description

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 Technical data Medium Working medium: Media temperature: Ambient temperature: Storage temperature: Operating pressure: Pressure rating: Leakage rate: 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). If the emergency power supply module (control module code A1, A2, Y1, Y2, Z1, Z2) is used, the maximum ambient temperature is reduced to 40 °C. MG = diaphragm size Kv values in m3/h Kv values determined...

Technical data MG = diaphragm size, Kv values in m3/h Kv values determined in accordance with DIN EN 60534, inlet pressure 5 bar, Ap 1 bar, with connection flange EN 1092 length EN 558 series 1 (or threaded socket DIN ISO 228 for body material GGG40.3) and soft elastomer diaphragm. The Kv values for other product configurations (e.g. other diaphragm or body materials) may differ. In general, all diaphragms are subject to the influences of pressure, temperature, the process and their tightening torques. Therefore the Kv values may exceed the tolerance limits of the standard. The Kv value curve...
