What is a Shuttle valve?

A shuttle valve is a valve that selectively allows fluid from two different input ports to flow through a system. It is primarily used in hydraulic circuits, where it allows fluid from one of two sources to be passed through based on pressure. The valve operates based on the higher pressure from one of the input lines, and only allows that fluid to flow through. Shuttle valves are commonly used in systems with multiple pressure sources to ensure stable operation by controlling the flow and improving energy efficiency. They are commonly found in machines that require multiple operating modes and can help enhance system reliability and functionality.

Application of Shuttle valve

✅ Hydraulic Systems
Shuttle valves are used in hydraulic systems where fluid is supplied from two different pressure sources. The valve ensures that only the fluid from the higher pressure source is allowed to flow through, optimizing system operation.
✅ Emergency Stop Circuits
Shuttle valves are also used in emergency stop circuits to control the fluid flow from multiple sources, ensuring the system can be safely shut down or controlled under high pressure conditions.
✅ Automobile Brake Systems
In vehicle hydraulic brake systems, shuttle valves help switch between two different brake circuits to maintain the best braking performance, ensuring safety during operation.
