A valve assembly including a valve having an opening and closing mechanism for controlling the flow of a fluid through the valve controlled by an actuator and an actuator mounting bracket secured to the valve. The actuator mounting bracket includes upper and lower clamps securing the valve actuator to the valve regardless of the valve position.

Exemplary embodiments are directed to butterfly valves, generally including a body assembly and handle assembly. The body assembly generally includes a body, a disc rotationally disposed inside an opening of the body, a cog, and a stem passing through the disc and the body. The handle assembly generally includes a handle body and a force ring. The stem can be rotationally interlocked relative to the disc and the handle assembly. The cog and the force ring can engage to rotationally secure the disc relative to the body. The handle assembly can include a lever and a grip, the force ring, the lever and the grip being pivotally secured relative to each other. The body can include a male radial protrusion and the body assembly can include a liner with a female radial groove. Methods of assembling and positioning a butterfly valve are also provided.

Embodiments of the disclosure generally relate to a flapper valve. The flapper valve may be used with processing chambers, such as semiconductor substrate processing chambers. In one embodiment, a flapper valve includes a housing having a first opening at a first end thereof and a second opening at a second end thereof, a first flapper pivotably disposed in the housing, and a second flapper pivotably disposed in the housing. The first and second flappers are movable to selectively open and close at least one of the first opening and the second opening.

Exemplary embodiments are directed to butterfly valves, generally including a body assembly and a locking cap. The body assembly generally includes a body, a disc rotationally disposed inside an opening of the body, a cog, and a stem passing through the disc and the body. The locking cap generally engages the cog to prevent rotation of the disc and the stem relative to the body. Methods of assembling and positioning a butterfly valve are also provided.

Exemplary embodiments are directed to butterfly valves, generally including a body assembly. The body assembly generally includes a body, a disc rotationally disposed inside an opening of the body, a bearing disposed inside the disc and the body, and a stem passing through the disc, the bearing and the body. The bearing generally includes an internal bearing edge. The stem generally includes an external stem edge to engage the internal bearing edge to prevent stem blowout from the body. Methods of assembling and positioning a butterfly valve are also provided.

Exemplary embodiments are directed to butterfly valves, generally including a body assembly and handle assembly. The body assembly generally includes a body, a liner disposed inside an opening of the body, and a disc rotationally disposed inside the opening of the body. The body generally includes a male radial protrusion within an inner surface of the opening. The liner generally includes a female radial groove along an outer surface to interlock the liner with the male radial protrusion of the body. Methods of assembling and positioning a butterfly valve are also provided.
