The AJ-type accumulator control and safety valve block is a multifunctional valve assembly used to safely control pressure flow between the accumulator and the hydraulic system, engage or disengage the accumulator from the circuit, and isolate it when necessary.

This block combines the shut-off valve, pressure relief port, gauge connection, and charging line within a single body, enhancing safety while simplifying installation. It enables fast and leak-free isolation of the circuit during accumulator maintenance, pressure adjustment, or system disconnection.
