Accumulator charging valve with relief valve

Quick Links

PRODUCT EXPLANATION
The accumulator charging valve is designed for installation
in an open center hydraulic system between the pump and
the downstream secondary hydraulic devices.
The accumulator charging valve supplies oil on demand to
the accumulator from the open center circuit. Accumulator
charging is accomplished at a preset rate (GPM) and is
relatively constant within the preset pressure limits.
The flow to the downstream secondary hydraulic devices will
be reduced fractionally for a short time when the accumulator
is charging. This does not noticeably affect the operation of
these components. Full system pressure is available to the
downstream secondary hydraulic devices at all times provided
oil delivery and pressure from the pump is not impeded.
IMPORTANT INFORMATION
A
Due to allowable operating temperature of accumulator
charging valve avoid contact or burn injury may occur.
B
Be sure system energy is relieved from accumulator
charging valve before removing from machine. See
machine operating instructions for procedures to relieve
system energy.

ACCUMULATOR
CHARGING VALVE
with Relief Valve
Product Explanation,
Operating Information,
and Service Instructions
The accumulator charging valve incorporates a full flow
relief valve to limit the maximum pressure in the hydraulic
system.
The accumulator upper and lower pressure limits, charging
flow rate, and the relief valve setting are set at the time of
manufacture.
OPERATING INFORMATION
End user must provide proper maintenance of valve, should
it become inoperable, by replacing the valve or servicing it
with the proper repair kit. See TABLE 1 on page 3 or TABLE 2
on page 5 for the proper repair kit number. Observe service
instruction procedures on following pages. See Warnings A, B,
C, and D below.
C
Relief valve is preset at the factory. DO NOT READJUST
or system damage or failure may occur.
D
Do not exceed the high limit pressure setting indicated
in TABLE 1 and TABLE 2 or system damage or failure
may occur.
