Wherever centrifugal pump is in application we can throttle flow, as in we can change the flowrate, but I have always seen gate valves at the discharge end of centrifugal pumps.
Why do we use gate valves at the discharge end as they are not good for throttling or controlling the flow, the disk of the gate valve gets eroded and the valve vibrates.
Why globe valves are not used?
