  • Retention mechanism for noise attenuation dome in fluid flow control device
    Patent number: 11041571
    Abstract: A fluid flow control device includes a valve body defining an inlet, an outlet, and a fluid flow path extending therebetween, a rotatable valve member at least partially disposed in the valve body, an attenuator operably coupled to the valve body, and a retention member disposed within the valve body. The rotatable valve member is rotatable within the fluid flow path from a shut-off position to an open position for controlling the flow of fluid through the fluid flow path. The attenuator defines an attenuator body that includes a plurality of noise-reducing apertures. The retention member is positioned against a portion of the attenuator body to retain the attenuator within the valve body.
