Accumulator Charging Valves

With over 70 years of proven design, the accumulator charging valves are built for heavy-duty mobile equipment. Providing energy efficient charging cycles that reduce operating costs that improves the proficiency of your application.



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.




Park Brake Valves

With Auto Apply

Provides added safety for operator and machine by controlling actuation of a spring apply, hydraulic release park brake. 

Valve senses accumulator brake pressure and automatically apply brakes at a predetermined pressure

Can function automatically and manually

Controls on/off function of spring apply/hydraulic release parking brake
