Abstract: A valve assembly comprising a rotary closure element which defines an axis of rotation and is selectively movable between a fully open position and a fully closed position. Mounted to and movable with the rotary closure element is an impedance assembly. The impedance assembly defines an inflow end and an outflow end, and comprises a plurality of fluid passageways which extend from the inflow end to the outflow end. Also partially defined by the impedance assembly is a flow opening which extends from the inflow end to the outflow end. The fluid passageways and the flow opening are oriented relative to each other such that a portion of a flow through the valve assembly is directed into the fluid passageways and a portion of the flow is directed through the flow opening when the closure element is in the fully open position.

Abstract: A valve assembly comprising a rotary closure element which defines an axis of rotation and is selectively movable between a fully open position and a fully closed position. Mounted to and movable with the rotary closure element is an impedance assembly. The impedance assembly defines an inflow end and an outflow end, and comprises a plurality of tortuous passageways which extend from the inflow end to the outflow end. Also fully or partially defined by the impedance assembly is an enlarged flow opening which extends from the inflow end to the outflow end. The tortuous passageways and the flow opening are oriented relative to each other such that a portion of a flow through the valve assembly is directed into the tortuous passageways and a portion of the flow is directed through the flow opening when the closure element is in the fully open position.

Abstract: A valve assembly comprising a rotary closure element which defines an axis of rotation and is selectively movable between a fully open position and a fully closed position. Mounted to and movable with the rotary closure element is an impedance assembly. The impedance assembly defines an inflow end and an outflow end, and comprises a plurality of fluid passageways of varying noise attenuating capability which extend from the inflow end to the outflow end. Also partially defined by the impedance assembly is a flow opening which extends from the inflow end to the outflow end.

Abstract: Disclosed is a blowdown valve for a boiler system for removing fluid that contains debris. The blowdown valve comprises a housing for a shutoff valve and a reversible throttle valve. The shutoff valve is fluidly connected to a fluid inlet that, in turn, is connected to the boiler system. Each one of the shutoff and throttle valves includes a rotatable valve ball having a bore formed therethrough. Rotation of the valve ball alternately blocks and unblocks fluid flowing therethrough. The throttle valve bore includes first and second bore ends. A bore insert is disposed within the bore between first and second debris zones. The bore insert includes passages configured for reducing fluid energy. The first and second debris zones entrap debris therewithin. The throttle valve reverses positions of the first and second debris zones such that entrapped debris may be flushed out of the fluid outlet.
