FR10-E40F Valve

FR10-E40F Valve symbol
A screw-in, cartridge-style, multi-function valve which includes a pressure- compensated,
non-adjustable hydraulic flow regulator valve with a vented port. With port 4 blocked, it can
be used as a priority-type flow regulator, delivering the pump flow to priority port 3 first,
then bypassing excess flow to port 2. With port 4 open, the spool shifts, allowing restricted
flow through vented port 4 and the remaining flow through bypass port 2.

The FR10-E40F maintains a constant flow rate from port 3 regardless of pressure variations
in the system downstream of priority port 3 or in bypass leg at port 2. The valve is intended
for use in an accumulator-charging circuit with an unloading valve piloting vented port 4.

• Built-in priority bypass functionality.
• Can be used in conjunction with an unloading valve for accumulator charging.
• Quiet, modulated response.
• Hardened parts for long life.
