Flow Control or Throttle Valves


Controls the flow passing through the valve.

Generally a sharp edged orifice or other restrictor.


Fixed or variable - fixed orifii provide constant flow or adjustable provide variable flow.

Pressure compensation - Without pressure compensation the flow will vary with changes in pressure either side of the orifice.
