19. What is the purpose of a Proportional flow divider and how does it work? 20. Which type of flow control valve should be used when very accurate speed control is required? regardless of the pressure and temperature changes? 21. The speed of the cylinder has been reduced by adjusting the flow control valve. What happens to the excess flow? 22. Where is the pilot pressure connected to in a reducing valve? Is it from the inlet port of the i valve or the outlet port? 23. Can you define Pressure drop across an orifice? 24. List three factors that effect the accuracy of actuator speed. 25. Describe what is opposing load? 26. Meter Out Circuit control the flow out of a cylinder by becoming an added in the circuit 27. In a bleed of circuit, the speed of the cylinder is controlled by diverting the extra flow from the pump to the tank through this component, 28. Pressure compensated flow control valve Automatically adjusts the response to changes in system pressure. 29. What is the only difference between a relief and an unloading valve? 30. In a regenerative circuit the pump output is 16 gpm. The system relief valve set at 1200 psi. in 30. In a regenerative circuit the pump output is 16 gpm. The system relief valve set at 1200 psi. Cylinder bore 4" rod dia. 2.75" stroke 24". a. Calculate Advance Speed using the regenerative method. b. Calculate time to extend 24 inches in seconds. c.
