ABSTRACT:
In order to provide a control valve for reducing the pressure of a fluid flowing through a system, while also achieving the pressure reduction in an acoustically damped manner, the flow control valve utilizes pressure reduction chambers for reducing fluid pressure in an incremental manner together with a porous insert associated with the pressure reduction chambers for acoustically damping noise generated during the pressure reduction. The flow control valve includes a valve housing having a valve chamber in direct fluid communication with a fluid inlet and having a plurality of spaced openings through which the fluid inlet communicates with the fluid outlet. By utilizing these components in the valve, the pressure reduction chambers can be disposed generally intermediate the valve chamber and fluid outlet, and the porous insert can be disposed between the pressure reduction chambers and the fluid outlet, whereby the porous insert in the hollow valve housing will further reduce fluid pressure in an acoustically damped manner upstream of the fluid outlet.
