The GEMÜ 649 eSyDrive 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 diagnosis purposes. Hermetic separation between medium and actuator Installation for optimized draining is possible Open/close function, positioner and process controller Force and speed are variably adjustable Extensive diagnostic functions Operable via web interface eSy-Web or Modbus TCP Various functions of add-on components and accessories are already integrated (e.g. position indicators, stroke limiters, etc.) Technical specifications Body configurations:2/2-way body | i-body | Multi-port body | T body | Tank valve body | Welding configuration Connection types:Clamp | Flange | Spigot | Threaded connection Connection standards:ANSI | ASME | BS | DIN | EN | ISO | JIS | SMS Body materials:1.4408, investment casting material | 1.4435 (316L), forged material | 1.4435 (BN2), forged material | 1.4435, investment casting material | 1.4539 (904L), forged material | EN-GJL-250, cast iron material | EN-GJS-400-18-LT, SG iron material Body lining:Hard rubber | PFA | PP Diaphragm materials:CR | EPDM | FKM | NBR | PTFE/EPDM Protection class:IP 65 Conformities:BSE/TSE | EAC | FDA | Oxygen | Reg.
