Shuttle Valve Series
I. Characteristics
This series of valves is constructed similarly to a combination of two check valves. It allows two pneumatic signals to be output separately from the same air inlet, thereby activating the valve and achieving the desired control function without any interference between the two pneumatic signals. The functionality of this method is equivalent to that of an "OR gate" in logic circuits.
