Abstract
A system includes a choke valve having a fluid inlet configured to receive a fluid at a first pressure and a fluid outlet configured to output the fluid at a second pressure. The choke valve also includes a fixed component and a movable component defining a throttling orifice between the fluid inlet and the fluid outlet. Additionally, the movable component is configured to automatically move relative to the fixed component in response to a change in the first pressure to maintain a consistent percent pressure drop between the first pressure at the fluid inlet and the second pressure at the fluid outlet.
