Abstract:
1. An actuator stem guide apparatus for use with a fluid valve actuator comprising: a base to be positioned inside a casing of the fluid valve actuator and to extend at least partially within a first opening defined by a biasing element positioned inside the casing, the base having a second opening to allow an actuator stem of the fluid valve actuator to tilt or lean within the base to enable a lever of the fluid valve actuator to rotate, an end of the base defining a guide receiving area adjacent the second opening of the base; and a first guide removably coupled to the guide receiving area of the base via a fastener that is received by the first guide and the guide receiving area, the guide being suspended adjacent the guide receiving area when the guide is coupled to the guide receiving area, the first guide having a first bearing surface defining a first profile to slidably engage the actuator stem to limit lateral movement of the diaphragm assembly relative to a longitudinal axis of the second opening to prevent the diaphragm assembly from engaging an inner surface of an actuator housing as the actuator stem moves between a first position and a second position, the first guide to be decoupled from the guide receiving area, and a second guide having a second bearing surface defining a second profile different than the first profile that is removably coupled to the guide receiving area when the first guide is decoupled from the guide receiving area.
