This set of Data communication and Networking Multiple Choice Questions and Answers (MCQs) focuses on “Data Link Layer – Data Link Control – Flow Control ”. For open control system which of the following statements is incorrect ? The ability to reduce or increase pressure in a system has a number of benefits. Normal valves have 3 flaps (leaflets), except the mitral valve. A control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller. Their selection and placement within a pneumatic circuit will greatly affect the function of an actuator. Flow rate varies as a faucet handle is turned clockwise or counterclockwise. c. both a. and b. d. none of the above. Q15. Handle orientation can be adjusted in 45° increments. This function is possible due to the capability of a flow control valve to affect the rate of energy transfer at any given point in a system by impacting the flow rate. The pressure reducing valve and the smothering of this valve are placed in series with each other. In some cases, these flow need to be controlled for reducing the entry of fluids to certain components. To know the function of a control valve … Pulmonary valve. Heat treated rotor and poppets provide positive fluid control. Ouestion a) What is a one-way flow control valve and how does it function. This valve is located between the right atrium and the right ventricle. Mitral valve. Operation.

Upvote (3) Downvote (0) Reply (0) A flow control valve having a pressure compensation function. Control valve CV refers to the flow coefficient of the valve. Manual Control Valve: 2-Position, 3-Port For use with single acting systems. Q16. In hydraulic systems, they’re used to control the flow rate to motors and cylinders, thereby regulating the speed of those components. a. flow control valve changes the direction of oil flow . 1) Throttle Valve, the hydraulic flow area can only be changed according to external instructions such as manual operation, mechanical or electronic control, so the actual flow through the valve is affected by the pressure difference across the valve. TCP IP MCQ Online Mcqs Test – Mobile Computing MCQ with Answers . This can be especially challenging to accomplish at very low operating pressures within a network. A pressure-compensated flow control valve has a fixed throttling flow at all pressures. Directional control valves can control the start, stop and change in direction of flow of a pressure medium. Overlapping of signals in pneumatic systems can be avoided by using a) Rolling lever valve b) Idle roller lever valve c) Both a and b d) None of the above. When Sizing (calculating which size valve is needed for your application ) a control valve specialist needs to calculate the flow coefficient. Flow dividers — A flow-divider valve is a form of pressure-compensated flow-control valve that receives one input flow and splits it into two output flows. a) Flow control valve b) Direction control valve c) Both a and b d) None of the above. Double-acting cylinder with one-way flow control valve. It is located in the control loop, an essential part of the water softening industry’s final control element. Answer & Explanation According to its function, it can be divided into shut-off valve, check valve, regulating valve, etc. With this type of control valve, there is only one direction where the flow control works.
