+ Contains a detent mechanism to close either one of the inlet ports, allowing flow between the opposite inlet and outlet.
+ The valve remains in that position until a predetermined shuttling pressure in reached.
Non-Detented Shuttle Valves
+ Allows the inlet with the higher pressure to be selected.
Bias Shuttle Valve
+ The valve is biased to close off one inlet port. The valve will reset to the same position once the inlet pressure to the non-biased port is reduced.
