Like pinch valves, the diaphragm completely seals off the actuating means from the process fluid, a benefit for valves in sanitary service. Key specifications include port configuration, port connections, valve size, media, and seal material The valve has flaps (cusps or leaflets) that open and close once during each heartbeat. In aortic valve regurgitation, the valve doesn't close properly, causing blood to leak back into the heart's main pumping chamber (left ventricle). As a result, the left ventricle holds more blood, possibly causing it to enlarge and thicken A leaking aortic valve allows blood to flow in two directions. Oxygen-rich blood either flows out through the aorta to the body - as it should - or it flows backward from the aorta through the defective valve into the left ventricle when the ventricle relaxes. Leaking valves can cause the heart to work harder to pump the same amount of blood

A leaky heart valve might go unnoticed. Or it could cause health problems that could be either minor or serious. How serious a leaky heart valve is depends on how much it interferes with normal. . A flow control valve regulates the flow or pressure of a fluid. Flow Control valves normally respond to signals generated by independent devices such as flow meters or temperature gauges. Control valves are normally fitted with actuators and positioners A gate valve opens by lifting a gate out of the path of the fluid. The distinct feature of a gate valve is that the sealing surfaces between the gate and seats are planar, so gate valves are often used when a straight-line flow of fluid and minimum restriction is desired. Gate valves are usually divided into two types: parallel and wedge-shaped
The mitral valve, also known as the bicuspid valve, helps move blood from the left atrium to the left ventricle. We'll go over its location, function, and anatomy. You'll also learn about the. A pressure relief valve is used to release excess pressure from a system during overpressure situations thus avoiding catastrophic failure. So, a Pressure relief valve is an important process safety device and widely used in chemical, petrochemical, power, and oil and gas industries. The pressure relief valve (PRV) is designed to open at a predefined set pressure Like all check valves, Swing check valves are used to avoid reverse flow in the pipe. The fluid pressure that passes through a system opens the valve, whereas the valve is closed by any flow reversal. The swing check valve functions by allowing the flow forces to push the closure part, it is a hinged clapper that rotates or swings around a supporting shaft Many different types of manual valves are used in industrial applications worldwide.
