Aerospace Hydraulic Fuses | Parker Stratoflex


In aerospace fluid conveyance systems for it is critical for the safety of the aircraft and passengers to prevent the loss of system pressure if a hose, tube, or other conveyance component ruptures or fails. Parker Stratoflex hydraulic fuses are carefully designed and constructed to close if the quantity or rate of flow reaches a certain threshold. Stratoflex hydraulic fuses provide reliability and peace of mind without restricting normal flow or operations, even in high-rate cycling applications such as brake anti-skid controls.

Parker Stratoflex offers three types of fuses: type one and type two fuses are considered quantity measuring, and type three is considered velocity measuring. Quantity measuring fuses react and close-off flow only after a certain quantity of fluid has passed through it, regardless of the rate of flow or pressure of the fluid. Velocity fuses react and close off flow when the fluid velocity or flow rate reaches or exceeds a certain threshold, regardless of system pressure or quantity of the fluid.

When safety is critical, trust the decades of engineering design and testing experience of Parker Stratoflex.
