Abstract: Provided are valve devices and flow heads for a valve device. A valve device can include a valve body (30) that opens and closes a valve hole (15a) to allow communication between a primary flow path (17a) and a secondary flow path (17b), a back pressure chamber (7) defined at the back side of the valve body, a small hole (51) that is provided in the valve body to allow the primary flow path of and the back pressure chamber to communicate with each other, and a pin (6) that has a straight portion inserted into the small hole to clean the small hole by relative motions of the small hole and the straight portion. A flow head (34) may be annular and include one or more notches along a perimeter and be configured to engage with an inner peripheral surface of an upper end portion of an inner barrel of the valve device.
