Features • Open/close function or with integrated positioner • Parameterisable and controllable via lO-Link • On-site or remote end position programming via programming input • Various functions integrated (e.g. feedback, stroke limiter, etc.) The GEMU R639 eSyStep 2/2-way diaphragm valve is electrically operated. The eSyStep electric actuator is available as On/Off actuator or with integrated positioner. An integral optical and electrical position indicator is standard. The self-locking actuator holds its position in a stable manner when idle and in the event of power supply failure. • Body configurations: 2/2-way body • Connection types: Flange l Flare l Solvent cement socket l Spigot l Threaded connection l Union end • Body materials: ABS l Inliner PP-H, grey / outliner PP, reinforced l Inliner PVDF / outliner PP, reinforced l Inliner PVDF/outliner PP, reinforced l PP, reinforced l PP-H, natural 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-R639

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 Medium 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 Pressure 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 purity...

Technical data Actuator version 1A with PTFE diaphragm can be used up to max. 4 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 and media temperature generate a combined temperature at the valve body which must not exceed the above values. Depending on the valve configuration, the maximum operating pressure of the pressure rating may be lower. Observe the operating pressure table. Kv values in m3/h MG = diaphragm size Kv values...
