Heavy Duty Priority Flow Control
The A-VRFC3C series provide a
simple and efficient way to supply
hydraulic power to auxiliary work
tools and attachments, especially
on earth moving machines such as
loaders and excavators.
These valves have a 3-way configuration:
one pump inlet port and
two outlet ports for priority and
by-pass flow. The priority port gives
fully pressure compensated
flow, power limited by a relief valve
and available on demand by energizing
the solenoid cartridge. Priority
flow rate and relief pressure are
adjustable. The inlet flow in excess
of the priority flow is directed to
the by-pass port.
Similar operation is found in the
two pumps version with two pump
inlets and one combined priority
port. Series A-VRFC2C is designed
for installation on load sensing
systems.
- Precise metering of the pressure
compensated flow independent
of all working pressures
- Solenoid actuated control to engage
priority flow with wide range
of connections and voltages
available
- Wide range of flow ranges and
port options
- Low leakage from priority outlet
with solenoid not energized
- Zinc plated, steel body for heavy
duty application
