Accumulator Charging Valves

Energy efficient charging cycles reduces operating costs that improves the proficiency of your application.

{{field.title}}

Providing reliable and efficient energy system management

With over 35 years of proven designs, the accumulator charging valves are built for heavy-duty mobile equipment. Used in open center and load sensing hydraulic systems, these valves can include various options such as a relief valve to limit main hydraulic system pressure.

Single Accumulator Charging Valve

Charges accumulator in a hydraulic brake circuit

Designed for installation in open center hydraulic systems, these valves use an internal spool valve to control hydraulic system flow to pressurize an accumulator.

Supplies oil to an accumulator from an open center circuit on demand at a preset rate

Remotely mounted from brake valves

Flow rates to 113 I/min (30 gpm)

Dual Accumulator Charging Valve

Charges accumulators in a dual hydraulic brake circuit

These valves monitor accumulator pressure and control hydraulic system flow to pressurize accumulators from two independent accumulator ports.

Load sensing options available

Uses power developed in the main hydraulic system

Built-in relief valve to limit the main hydraulic system pressure

Accumulator Charging Valves With Relief

Single and Dual

The function of these charging valves with relief is the same as either the single or dual charging valves above. However, a main hydraulic system relief valve is incorporated.

Accumulator Charging Valves with Load Sensing

Single and Dual

Load sensing charging valves send a load sense signal to a load compensated pump creating energy efficient circuits. The charging function is the same as the single or dual charging valves, and is used in load sensing hydraulic circuits.
