Shuttle valve

Shuttle valve

Valve equivalent to two check valve combinations

It has the function of logic "or gate", which is widely used in logic circuit and program control circuit, and is commonly used in manual - automatic circuit conversion.

Because there is a path through process in the shuttle valve during the reversing process, when the intake or exhaust volume of a certain interface is very small, the pressure difference between the front and rear of the valve can not cause the normal reversing of the valve, which makes the valve not completely reverse and stops halfway, resulting in the valve action failure. Therefore, when using, it is noted that the path is too small if the reducer is used at a certain interface.
