Beschreibung
Zusammenfassung:	A valve apparatus comprises a valve body defining a flow path therethrough, a valve member mounted within the valve body, and an actuator assembly mounted internally within the valve body. The actuator assembly comprises a piston bore and piston member defining a piston chamber therebetween, wherein at least one of the piston bore and piston member is engaged or associated with the valve member such that the valve member is moveable in accordance with fluid pressure within the piston chamber to selectively occlude the flow path.
