Flow through a valve
WebThe control of flow through a pipe requires mainly three devices-a flowmeter for the measurement of flow, a control valve to control the flow, and a controller. The controller gives an appropriate signal to the control valve depending upon the difference between the measured flow rate and the set flow rate. Conventional flowmeters produce a differential … WebMar 11, 2024 · The mitral valve is one of four valves in the heart that keep blood flowing in the right direction. Each valve has flaps (leaflets) that open and close once during each heartbeat. If a valve doesn't open or close …
