Quiz on Chapter 13: Flow Controls and Flow Dividers

1. A needle valve controls flow in:

1. both directions.
2. one direction.
3. neither direction.

2. Pressure-compensated flow control valves maintain a constant flow:

1. because they have a special needle valve.
2. when pressure stays under 2000 psi.
3. because they maintain a constant pressure drop across the orifice.

3. A 3-port flow control:

1. can control different flows to several actuators at once.
2. can only control one actuator at a time
3. operates at maximum pressure for the whole cycle.

4. A 50-50 spool-type flow divider valve can:

1. split flow in both directions.
2. only split flow in one direction.
3. is not used to split flow.

5. A priority flow divider’s priority outlet:

1. changes flow as inlet flow changes.
2. changes flow as inlet pressure changes.
3. has constant flow when inlet flow is equal to or greater than its volume.

6. Pressure at the inlet of a spool-type flow divider is:

1. equal to the lowest outlet pressure.
2. equal to the highest outlet pressure.
3. equal to the average of the sum of the outlet pressures.

7. Motor flow dividers use:

1. hydraulic motors in series to split flow.
2. hydraulic motors in parallel to split flow.
3. flow control valves to split flow.

8. Pressure at the inlet of a motor flow divider is:

1. equal to the lowest outlet pressure.
2. equal to the highest outlet pressure.
3. equal to the average of the sum of the outlet pressures.

9. This symbol is for a:

1. motor flow divider.
2. priority flow divider.
3. spool-type flow divider.
