The Hydraulic Sequence Check Valve controls hydraulic flow so that connected components operate in a specific order. It opens only when system pressure reaches a set level, allowing the next function in the circuit to activate at the correct time. The built‑in check valve prevents reverse flow, helping protect lines, cylinders, and control elements from back‑pressure effects. The valve maintains stable pressure transitions and helps avoid unplanned movements when multiple hydraulic functions share the same supply.Attributes:• Controls hydraulic flow activation based on preset pressure.• Ensures correct sequencing of hydraulic components.• Maximum valve leakage rated at 1 drop per minuteApplications: The Hydraulic Sequence Check Valve is installed in hydraulic circuits that require controlled activation order and backflow protection. It helps maintain correct sequence timing, prevent reverse flow, and support consistent operation of cylinders, actuators, and manifold‑based hydraulic functions.
