Collets for coupling rotary actuators to valves are disclosed. An example collet includes a plurality of flexible members configured to be coupled to an elongated member and each having an inner surface that forms at least a portion of a substantially rectangular bore configured to receive a rectangular shaft. The plurality of flexible members form an involute outer surface for engaging an involute inner surface of an opening of a lever. The opening of the lever is configured to cause the plurality of flexible members to be displaced toward an axis of the elongated member to cause the inner surface of each of the plurality of flexible members to engage one or more surfaces of the rectangular shaft.

Collets for use with valves

The present invention comprises a method for separating hydrocarbons from catalyst fines in a slurry oil/catalyst fines/diluent mixture (SCDM) comprising the steps of removing SCDM from a slurry oil storage tank and combining the SCDM with crude oil entering a desalter in order to separate the slurry oil from the catalyst fines, whereby the desalter causes the hydrocarbon content of the SCDM to exit the desalter with dehydrated hydrocarbon from the crude oil while catalyst fines exit the desalter with basic sediment and water removed from the crude oil.

A three-piece fluid control valve configuration including a valve body, a ball control member and two tailpieces that connect the valve to a pipeline and also house the ball fluid seals. Respective bearing plates with trunnion bearings are guide pin mounted between the respective tailpieces and in supporting engagement with respective trunnions on the ball control member for rotatably supporting the ball. A shaft bearing supports a valve shaft having a splined drive end engaging splines in one of the ball trunnions. Bidirectional fluid flow is enabled with ball sealing members on each ball side, with the sealing member on each side replaceable by removing the tailpiece on that side.

Throttling control in a fluid control valve

A rotary valve noise attenuator with a rotary ball control element and a noise attenuator member mounted in the ball having multiple, elongated, substantially enclosed channels formed across the valve opening to split the flow stream into several smaller flow streams. The channel walls are perforated so each smaller flow stream is further dispersed and diffused into many minute flow streams after entering the channel. A noise attenuator constructed of several corrugated sections fixed crest to crest to form several diamond shaped channels across the valve opening each having four side walls with holes.

Rotary noise attenuator

A control element for a fluid valve includes a main body having a rounded outer surface on a first side, an inner base surface and first and second opposed inner side surfaces adjacent the inner base surface on a second side. First and second ears are joined to the main body at spaced locations and extend away from the main body on the second side thereof. The ears include opposed inner surfaces adjacent the inner side surfaces of the main body. The inner surfaces together form opposed passage surfaces which diverge from one another at first and second ends to improve flow efficiency.
