Abstract
A suck back valve is equipped with a second valve by which a flow amount of a pressurized fluid, which is sucked by a third diaphragm, is electrically controlled based on an output of activation and deactivation signals from a main controller. The suck back valve further includes an encoder which detects a displacement amount of the third diaphragm, and outputs a detection signal thereof to the main controller.
