Parker’s K04G3 shuttle is typically used mobile braking circuits where two accumulators are used. It serves two functions: Ensuring that the accumulators are charged equally and at the same rate, and as a guard against pressure loss should one of the accumulators fail. Connected to the main supply source, the K04G3 will divide flow between two hydraulic accumulators and charge them to be used as an auxiliary source of power for braking circuits. Used in conjunction with a check valve and unloading valve (Parker RU101), the accumulators charge to a preset pressure and will unload the charge pump, or divert flow to other parts of the system. In the event one of the accumulators fail, the K04G3 valve will shift to protect the good one. Parker’s K04G3 is rated for 30 LPM (7.9 GPM) and up to 350 Bar (5000 PSI).
