Reliable shuttle valve suited to provide redundancy in pilot circuits for actuation of larger components.
The 1/4” GEN2 Shuttle Valves act as flow logic components that allow the automatic selection of flow from two supply (inlet) ports to be directed through a common function (outlet) port.
They have been redesigned with significant improvements, that fit within the same footprint as the legacy 1/4” Disc Shuttle Valve, yielding an order of magnitude improvement in cycle life.
