Which of the following is true about a sequence valve? Sequence valves: A. Allow a check valve to override its normal operation B. Controls the rate of air flow in a pneumatic system C. Direct air flow to a different area in a circuit when actuated by pressure level D. Open and close the intet and outlet ports in a pneumatic system
True or false As fluids flow through pipes energy is lost due to friction which produces a pressure differential
Select the correct optionFormerly it was very common to determine the capacity of a valve; however, it is currently deprecated as it is unreliable a) Fluid directional limitb) Flow factorc) Compression ratiod) The diameter of its ports
Identify and explain the valve allowing the fluid to flow only in one direction with the help of neat diagrams.
Which of the following statements is not true? Normally the desired valve face-to-seat contact area for intake valves is 1 inch. Normally the desired valve face-to-seat contact area for exhaust valves is 1 inch. The average valve seat width is 0.060 inch and the average seat begins 0.030 inch from the valve margin. A properly reconditioned seat has the correct seat width and sealing position on the valve face.
