FR10-30F Valve

SYMBOL:
FR10-30F Valve symbol

DESCRIPTION
A screw-in, cartridge-style, non-adjustable, pressure-compensated, hydraulic flow regulating
valve intended for use in fixed displacement hydraulic circuits requiring partial pump flow
diversion on a priority basis.

OPERATION
The FR10-30F maintains a constant flow rate out of port 3 regardless of load pressure changes
in the circuit downstream of port 3, or in the bypass leg at 2.
The valve’s spool maintains a constant differential pressure of 6.5 bar (95 psi) across a fixed
internal orifice, thereby regulating the hydraulic flow rate from 1 to 3.
The FR10-30F is a priority type regulator, delivering the pump flow to 3 first, then bypassing
excess to 2. All ports may be fully pressurized.
Flow out of priority port 3 may vary based on input flow amount, particularly with lower
temperatures and increased fluid 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.
   Inlet pressure at port 1 begins to rise over the compensating differential
   when bypass flow exceeds 22.7 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 100°C (-40° to 212°F) with Buna seals;
   -26° to 204°C (-15° to 400°F) with Fluorocarbon seals
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
