WebOct 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. For applications such as pneumatic tools and motors which need to be lubricated, that lubrication should consist of light oiling to prevent clogging these devices. WebA shuttle valve allows two alternate flow sources to be connected in a one-branch circuit. The valve has two inlets P1 and P2 and one outlet A. Outlet A receives flow from an inlet that is at a higher pressure. Figure 1.5 shows the operation of a shuttle valve.

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… WebThe top symbol shows a directional control non-return valve function with a replaceable orifice restrictor fitting in the internal pilot supply flow.
