Product Introduction：

AJ type accumulator control valve group, installed between the accumulator and hydraulic system, controls the on-off of the accumulator, pressure overload protection, and pressure relief and oil discharge. The composition and functions of each component are: manual ball valve - oil on/off; threaded plug-in direct acting relief valve - pressure overload protection; For globe valves or ball type electromagnetic directional valves - pressure relief and oil discharge. In order to release pressure and oil from the accumulator when there is no electricity, the electronic control valve group still retains a needle shaped shut-off valve. The AJ type control valve group has the characteristics of reliable performance, beautiful appearance, compact structure, and convenient operation.
