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....

Technical data - Diaphragm valve Working medium: Media temperature: Ambient temperature: Storage temperature: Corrosive, inert, gaseous and liquid media which have no negative impact on the physical and chemical properties of the body and diaphragm material. Pressure values dependent on the material All pressures are gauge pressures. Operating pressure values were determined with static operating pressure applied on one side of a closed valve. Sealing at the valve seat and atmospheric sealing is ensured for the given values. Information on operating pressures applied on both sides and for high...

Technical data - Diaphragm valve 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...
