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… high isle furnishing esoWebOct 13, 2024 · This valve typically acts as a safety device by relieving pressure from motion-causing pneumatic devices, such as cylinders and actuators, when an emergency stop is pressed.
