1/4” GEN2 Disc Shuttle Valve | Technical Marketing Sheet
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. FUNCTIONAL DESIGN SPECIFICATIONS 1/4”
