1

Pressure compensated flow control

Maintains a steady pressure drop across orifice

2

What determines the pressure drop across orifice in compensated valve

Compensator spring

3

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

4

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

5

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

6

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

Proportional flow control valve
