The basic structure of a shuttle valve is like a tube with three openings; one on each end, and one in the middle. A ball or other blocking valve element moves freely within the tube. When pressure from a fluid is exerted through an opening on one end it pushes the ball towards the opposite end. This prevents the fluid from traveling through that opening, but allows it to flow through the middle opening. In this way two different sources can provide pressure without the threat of back flow fr… WebSep 23, 2008 · The complete symbol gives more information about the valve function and helps with troubleshooting and valve replacement.

WebThe valves prevent the backward flow of blood. These valves are actual flaps that are located on each end of the two ventricles (lower chambers of the heart). They act as one-way inlets of blood on one side of a ventricle and one-way outlets of … When the shuttle valve is in the normal operation place, the pneumatic or hydraulicsupply has a free flow from the normal inlet port, through the valve. Afterward, flow is passed out through the outlet port to the actuating unit, it may be a pneumatic or hydraulic cylinder. The operation is very simple … See more In a particular special application, the supply of pneumaticor hydraulic fluid to a subsystem must be from more than one source to meet … See more The figure below shows the cutaway view of a typical shuttle valve.
