ABSTRACT:
A fluid pressure actuator assembly (44) adapted for use with a valve member (42) is disclosed, the actuator being of the type comprising a housing assembly (50), and an axially moveable diaphragm assembly (56). A linkage member (48) is operably associated with said diaphragm assembly and extends axially through a linkage opening (70), and is connected to a valve member (42). A preload member (74) includes a generally annular preload portion (76) between a stop surface (55) and the diaphragm assembly (56), and in engagement with both. The preload portion (76) maintains the diaphragm assembly (56) in a position corresponding to a first position of said valve member (42), in opposition to the force of a biasing means (68). The preload member (74) includes a handle portion (78) extending axially through the linkage opening (70) whereby, after said linkage member (48) is connected to said valve member (42), the preload member (74) may be removed from the actuator through the linkage opening (70), by means of the handle portion (78).
