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 a pressure reduction chamber for reducing fluid pressure in an incremental manner together with a valve member having a porous insert for acoustically damping noise generated during the pressure reduction. The flow control valve includes a valve housing having a valve chamber intermediate a fluid inlet and a fluid outlet through which the fluid inlet communicates with the fluid outlet. By utilizing these components in the valve, the pressure reduction chamber can be disposed generally intermediate the fluid inlet and valve chamber, and the hollow valve member can be disposed in communication with the pressure reduction chamber, whereby the porous insert in the hollow valve member will further reduce fluid pressure in an acoustically damped manner upstream of the fluid outlet.
