Abstract: Apparatus to connect a valve stem to a valve member are disclosed. An example apparatus includes a valve stem having a laterally extending opening, a valve member having a laterally extending opening, and a coupling having adjacent one end an extension received in the laterally extending opening of the valve stem and adjacent an opposite end an extension received in the laterally extending opening of the valve member. A resilient member is located between the valve stem and the valve member.

Abstract: A diaphragm for use with a valve includes a body having a central portion including an outer central portion and offset by an angled portion from an outer portion. The central portion is to be disposed at a position adjacent a valve seat and displaced into engagement with the valve seat to affect fluid flow. The body deforms substantially at the outer central portion and angled portion during displacement of the central portion by the valve and reacts substantially unilaterally to prevent vibration of the diaphragm during fluid flow past the valve seat.

Abstract: Spacers for use with actuator casings are disclosed. An example spacer includes a ring-shaped member defining a central opening and configured to form a part of an actuator casing and to space first and second actuator casing portions a predetermined distance when the first and second casing portions are coupled to the ring-shaped member. The ring-shaped member includes a first surface surrounding the central opening configured to engage the first casing portion and a second surface surrounding the central opening configured to engage the second casing portion. Each of the first and second surfaces includes a plurality of apertures configured to receive threaded fasteners to attach the first and second actuator casing portions to the ring-shaped member.
