Features • Hermetic separation between medium and actuator • Installation for optimized draining is possible • Open/Close function, positioner and process controller • Actuation force and actuating speed variably adjustable • Operable via web interface eSy-Web and Modbus TCP • Extensive functions, such as position feedback, diagnostic functions and opening and closing stroke limitation The GEMU R649 diaphragm valve is actuated by a motorized hollow shaft actuator. It is based on technology that does not use brushes or sensors and therefore guarantees high performance and a long service life. In addition to Open/Close applications, the valve is ideal for variable and complex control applications. The actuator has an integrated web server for parameterization and diagnostics purposes. • Body configurations: Straight through body • Connection types: Flange l Flare l Solvent cement socket l Spigot l thread l Union end • Connection standards : ANSI l BS l DIN l EN l ISO l JIS • Body materials: ABS l Inliner PP-H, grey / outliner PP, reinforced l Inliner PVDF/outliner PP, reinforced l PP, reinforced l PP-H, natural l PVC-U l PVDF • Diaphragm materials: EPDM l FKM l NBR l PTFE/EPDM Technical data depends on the respective configuration further information webcode: GW-R649

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 Working medium: Media temperature: 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 Ambient temperature: Valve body material Storage temperature: Operating pressure: 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 Leakage rate:Pressure/temperaturecorrelation: Leakage rate A to P11/P12 EN 12266-1 Actuator version 0E with PTFE diaphragm can be used up to max. 5 bar. At temperatures above 30 °C the maximum operating pressure decreases. Actuator version 1A in conjunction with diaphragm size MG 40 is limited to 5 bar operating pressure. In conjunction with a PTFE diaphragm to 2 bar. At temperatures above 30 °C the maximum operating pressure decreases. The pressure rating (PN) depends on the diaphragm size. Data for extended temperature ranges on request. Please note that the ambient temperature...
