The QFZ-type accumulator safety shut-off valve group is designed to safely isolate hydraulic accumulators from the system, control pressure, and ensure safety during maintenance operations. Installed between the accumulator and the hydraulic circuit, it allows the opening and closing of fluid flow while offering a multifunctional structure for pressure relief, charging, and gauge connection.

With its compact design, leak-proof valve mechanism, and integrated safety structure, it protects the accumulator against overpressure and enables maintenance to be performed without shutting down the entire system. It is reliably used in industrial press lines, hydraulic power units, and mobile machinery.
