Spesifikasi KOFLOC High Grade Metal Flow Controllers MODEL 5100 SERIES
MODEL 5100 SERIES
Features
-High accuracy and high response are achieved by the flow sen-sor with temperature- following current difference detection.
-A normally-closed solenoid valve is employed.
-A low leak rate is achieved by the weldless structure and metalseal.
-The dead volume is reduced thanks to the diaphragm seat valve.
-The face-to-face and body dimensions and the wiring tie-inpoints are designed to facilitate replacement of devices made by other companies.
