Pressure compensated flow control

Maintains a steady pressure drop across orifice


What determines the pressure drop across orifice in compensated valve

Compensator spring


Bypass type pressure compensated valve

Extra oil is dumped back to the tank to control the inlet pressure.
mostly used with fixed displacement pumps
Have 3 ports


Restrictor type pressure compensated valve

Has 2 ports
Extra pressure builds up at inlet and causes pump to de-stroke
mostly used with variable displacement pumps


Priority flow divider

Do not have a variable orifice
Compensator is normally closed
Can find a circuit relief that will be set slightly less then system so that if you dead head primary, you wont lose secondary


The flow control valve that splits a single flow among 2 or more circuits is?

Proportional flow control valve
