Features • Compact system design due to flow-optimized high-flow valve bodies • Lockable handwheel optionally available • Position feedback optionally available • Integral optical position indicator The GEMU R677 2/2-way diaphragm valve has a low maintenance plastic actuator and is manually operated. An integrated optical position indicator is standard. The high-flow valve body provides compact dimensions at high flow rates. • Body configurations: Straight through body • Connection standards : ANSI l ASTM l BS l DIN l EN l ISO l JIS • Connection types: Flange l Spigot l Union end • Body materials: ABS l Inliner PP-H, grey / outliner PP, reinforced l Inliner PVDF/outliner PP, reinforced l PP, reinforced l PVC-U, grey l PVDF • Diaphragm materials: EPDM l FKM l NBR l PTFE/EPDM Technical data depends on the respective configuration further information webcode: GW-R677

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....

Order data

Technical data Working medium: Ambient temperature: Storage temperature: Operating pressure: Corrosive, inert, gaseous and liquid media which have no negative impact on the physical and chemical properties of the body and diaphragm material. Valve body 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 purity media on request. Pressure rating:...

Technical data Product conformity Pressure Equipment Directive: Drinking water: MG = diaphragm size Kv values in m3/h Kv values determined acc.to DIN EN 60534 standard, inlet pressure 5 bar, Ap 1 bar, PVC-U valve body 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 (Kv value dependent on valve stroke)...
