Abstract
A control system may include a fluid conduit configured to direct fluid discharged from a fluid pump. The control system may include a shutoff valve and a throttling valve in the fluid conduit. The control system may include a controller configured to cause, while the shutoff valve is closed, actuation of the throttling valve to an open position. The controller may be configured to obtain first information indicating a first pressure of the fluid in the fluid conduit at a first side of the throttling valve between the throttling valve and the shutoff valve and second information indicating a second pressure of the fluid in the fluid conduit at a second side of the throttling valve. The controller may be configured to transmit a signal to indicate that the shutoff valve has a leak based on the first pressure being different from the second pressure.
