PURPOSE: A valve equipped with a gasket-integrated diaphragm is provided to keep the airtightness of an actuator without using a separate gasket. CONSTITUTION: A valve equipped with a gasket-integrated diaphragm comprises an actuator and a diaphragm(52'). The actuator controls the opening and shutting of a flow channel. The diaphragm is coupled inside the actuator. The diaphragm power converts power supplied from the outside to the inside of the actuator into mechanical output. The diaphragm delivers the mechanical output to a stem. The diaphragm comprises an airtight band. The airtight band performs the airtightness maintenance function of the actuator.
