The Shuttle Valve, also known as a double-check valve, is used to enable pressure in a hydraulic or pneumatic system to be obtained from alternative sources, ensuring uninterrupted operation. It consists of a housing with three ports and a cavity that houses a poppet, which shifts within the cavity to control the flow direction. When one source is unavailable or needs to be bypassed, the poppet shifts to allow pressure from the other source to maintain system function.Attributes:• Features three ports and a cavity for efficient flow control.• Prevents over-pressurization by balancing multiple sources.• Provides quick and efficient pressure switching without system interruption.Applications: The Shuttle Valve is used to source pressure from alternate supplies, ensuring continuous operation by automatically switching between sources when one becomes unavailable.
