FLOW CONTROLS
FR10-30F Regulator, Pressure-Compensated
DESCRIPTION
A screw-in, cartridge-style, pressure-compensated, non-adjustable fl ow regulator,
intended for use in fi xed displacement hydraulic circuits requiring partial pump fl ow
diversion on a priority basis.
OPERATION
The FR10-30F maintains a constant fl ow rate from ➂ regardless of load pressure
changes in the system downstream of
➂, or in the bypass leg at ➁.
The valve’s spool maintains a constant differential pressure of 6.5 bar (95 psi) across
a fi xed internal orifi ce, thereby regulating the hydraulic fl ow rate from
➀ to ➂.
The FR10-30F is a priority type regulator, delivering the pump fl ow to
➂ fi rst, then
bypassing excess to
➁. All ports may be fully pressurized.
Flow out of priority port
➂ may vary based on input fl ow amount, particularly with
lower temperatures and increased fl uid viscosities. Settings may need to be
established through correlation study. Consult factory.
FEATURES
• Hardened parts for long life.
• Quiet, modulated response.
• Industry common cavity.
RATINGS
Operating Pressure: 207 bar (3000 psi)
Flow Rate: 22.7 lpm (6.0 gpm) max. regulated; 37.8 lpm (10.0 gpm) max. input.
Pressure at
➀ begins to rise higher than compensating pressure differential
when bypass fl ow exceeds 23 lpm (6 gpm).
Standard Compensator Bias Spring: 6.5 bar (95 psid) differential
Flow Maintenance Setting Range: 0.4 to 5.9 lpm (0.10 to 1.5 gpm)
to accuracy of ±15%; 6 to 22.7 lpm (1.6 to 6.0 gpm) to accuracy of ±10%
Temperature: -40 to 120°C
Filtration: See page 9.010.1
Fluids: Mineral-based or synthetics with lubricating properties at viscosities of
7.4 to 420 cSt (50 to 2000 sus); See Temperature and Oil Viscosity, page 9.060.1
