The load-sensitive accumulator charge valve is designed for load-sensitive systems. When the accumulator needs to be replenished, the control part of the valve sends a pilot signal to the load sensing pump. It can maintain the pressure and volume in the accumulator and make the pump stand by when the system does not need flow.
The accumulator charge flow and the upper and lower accumulator pressure limits are set during production.
