Description
The FR10-E40F is a screw-in, cartridge style, pressure compensated, non-adjustable hydraulic flow
regulator valve with a vented port option. 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 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
Operation
The valve 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 of FR10-E40F
Features
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.
