GF e-DIASTAR Diaphragm Valve for Types 514, 515 and 517

GF e-DIASTAR Diaphragm Valve for Types 514, 515 and 517 system is based on the diaphragm Valve Type 514 (threaded sockets) and Type 515 (spigots), on which the electric actuator EA-MT is mounted. The diaphragm Valve Type 517 (flange) can be retrofitted after installation. The electric actuator EA-MT opens and closes the diaphragm valve fully automatic. The e-DIASTAR is used to regulate, close and control volume flows automatically. Especially when transporting contaminated, aggressive or abrasive media, this type of valve has decisive advantages thanks to its simple function and optimized construction. Only the valve body and the replaceable diaphragm are in contact with the medium. Applications: • Chemical process industry • Microelectronics • Water treatment • Cooling • Control applications Actuator benefits/features: • Multiturn actuator • Adjustable integrated heating • 7-segment error display • Position feedback (open/close) • Fully automatic end position teach-in • Integrated emergency manual override • Retrofit set includes: Conversion kit with drive, half shells and screws Valve benefits/features • Full plastic valve without metal screws • No corrosion due to aggressive media/environment • Constant leak-tightness in the event of changes in temperature without tightening screws • Plastic-appropriate, highly stable connection of upper part and valve body by means of a buttress thread • Maximum flow and linear characteristic curves for easier control • Diaphragm geometry for longer service life Flow media • Contaminated, solid or ultrapure media
