What is a Shuttle valve?

A shuttle valve consists of a movable part called a shuttle, two input ports (port A and port B), and one output port. In the initial state, the shuttle is in the neutral position, port A and output port are connected, and port B is closed. When fluid is supplied from port A, the shuttle is pushed by the fluid and connects port A and the outlet port. On the other hand, if fluid is supplied from port B, the shuttle is pushed by the fluid and connects port B and the outlet port. This mechanism allows the shuttle valve to switch the flow to the output port depending on the direction of fluid supply.

Shuttle valves are made of materials such as aluminum, and the valve body is made of nylon or synthetic rubber. A small amount of leakage may occur from the valve, which makes it unsuitable for use as a stop valve. However, it is still widely used in various industries due to its simple structure, high reliability, and flexibility in control processes.

When selecting a shuttle valve, it is necessary to carefully select it according to the requirements such as the fluid used, pressure, connection size, and material. By considering these factors, you can choose the most suitable shuttle valve.

Application of Shuttle valve

Shuttle valves have a wide range of applications in fluid control, providing directional control of fluids in the following areas:

hydraulic unit
In hydraulic systems, shuttle valves are responsible for directional control of fluid. Specifically, it is used to send fluid from a hydraulic pump to a hydraulic cylinder, hydraulic motor, etc. Shuttle valves allow you to control the movement of actuators and perform specific operations.

Transport equipment
Widely used in many transportation equipment such as automobiles and railway vehicles. For example, in a hydraulic brake system, a shuttle valve transmits braking pressure to the brake cylinder, which applies braking force to the brake disc. This allows the vehicle to brake.

chemical plant
Helps adjust the required liquid formulations for specific chemical or manufacturing processes. It is used to mix different chemicals to accelerate reactions, providing precise mixing of liquids from different fluid sources in a predetermined proportion.

In these applications, shuttle valves provide directional control of fluid and enable precise operation of processes and equipment.
