Typical application pressure (all ports) 210 bar (3000 psi)
Maximum regenerative flow 57 L/min (15 USgpm)
Regeneration diminishes progressively above setting of CBV1-10
Temperature range -40° to 120° C (-40° to 248° F)
Fluids All general purpose hydraulic fluids such as:
MIL -H-5606, SAE 10, SAE 20, etc.
Operation
This standard valve package
provides means for fast exten-
sion of a cylinder at low pres-
sure without additional pump
flow. This package diverts rod
end flow to the head end in
order to accelerate the load.
When the load induced pres-
sure reaches a predetermined
level, the valve closes off. Rod
end oil is automatically divert-
ed to tank and the full pump
pressure is applied, allowing
maximum force to develop at
lower speed.
When applying pressure
sensitive regenerative valves
consider the following: Rod to
diameter ratio. The pressure
required to move a cylinder.
Losses due to high flows and
seal friction may prevent a
circuit from staying in regen-
eration.
Features
Automatic kick out of regen-
erative operation made via
load pressure sensing. Tamper
proof and adjustable pres-
sure setting options. Provides
a smooth transition and
decrease of the regenerative
flow through use of a counter-
balance valve. Provides manual
override on POC cartridge to
lower the load in the event of
power loss. Aluminum in-line
type housing.

Application Notes
Formulas to calculate ow in regeneration circuits are:
(where Db = Bore Diameter and Dr = Rod Diameter)
Combined Flow Db²
(pump ow plus = X Pump Flow
regenerative ow) Dr²
Regenerative Flow Db² - Dr²
(ow out rod end) = X Pump Flow
Dr²
Retraction Flow Db²
(ow out of the bind = X Pump Flow
end during retraction) Db² - Dr²
Note:
This valve package should not
be used as a load holding or
load lowering control valve.
