Accumulator Charging Valve Series AGSF

The series AGSF accumulator charging valve is a twostage, high-performance flange-mounting valve with an interface to SAE J518 code 61 and ISO 6162-1. The main components of the valve are a body and a mechanically self-operated two-stage pressure-unloading cartridge. The accumulator charging valve is a cartridge unit with a seated pilot stage and a spool-type main stage and leak-free balltype pilot stage. The changeover to unloaded bypass is a soft-switching one, with damped switching characteristics. Accumulator charging valves are used wherever a pump has to be disconnected from and re-connected to a pressure circuit. For this purpose, either the ‘Off’ pressure or the ‘On’ pressure of the cartridge can be set. When the ‘Off’ pressure is set, the ‘On’ point will depend on the selected percentage on-off pressure differential, or the other way round
