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 coun-
terbalance valve. Aluminum
in-line type housing.
