Flow Controls
Fluid Power Flow Basics
| Question | Answer |
|---|---|
| Flow is affected by? | Changes in Temperature Pressure,Load, Orifice Size |
| Pressure differential across an orifice | Affects Flow |
| A Fixed orifice is used when? | FLow is not critical |
| The advantages of meter out speed regulation are? | Overrunning load control and Partially control actuator leakage. |
| A flow control device can be? | Fixed or Variable |
| A Needle Valve with a check valve attatched is a? | One way flow control |
| A Pressure Compensated flow Contrl Valve will? | Maintain a set flow rate regardless of changes in Pressure. |
| What valve is used to maintain a set rod speed regardless of changes in temperature or pressure. | Pressure and Temperature Compensated flow Control Valve |
| Provides Overrunning Load Control. | Meter out flow Control |
| Sets speed of actuator extent. | Meter in Control |
| Is set in Parallel to the system provides reduced heat generation and does not provide Overrunning Load Control. | Bleed off flow control |
| Provides equal and unequal rates of flow to two seperate circuits. 50/50 to 90/10 | flow Divider |
| An orbitrol steering valve system will contain? | Flow Divider, Orbitrol steering Valve, Crossport Relief valves, Cylinders, and Main Circuit relief. |
| Pressure Intensification in a meter out circuit will occur because? | pressure is reacting to different surface areas in an unbalanced Cylinder |
| Meter in and Meter out flow control methods will generate? | Excessive heat |
