Topic: Re: Determine valve type

posed by 
I would not consider myself a valve expert, but I would suggest that any valve that is going to be used for pump-throttling purposes will have a tendency to create considerable turbulence upstream of the valve. In view of this, the valve should be located in a discharge pipeline that is at least one size larger than the pump discharge nozzle, and at a considerable distance from the pump in order that the pump be protected from the turbulence that will be created.
