A screw-in, cartridge-style, pressure-compensated, non-adjustable flow regulator, intended for use in fi xed displacement hydraulic circuits requiring partial pump flow diversion on a priority basis.
The FR08-30F maintains a constant flow rate from ➂ regardless of load pressure changes in the system downstream of ➂, or in the bypass leg at ➁The valve’s spool maintains a constant differential pressure of 6.5 bar (95 psi) across
a fi xed internal orifice, thereby regulating the hydraulic flow rate from ➀ to ➂The FR08-30F is a priority type regulator, delivering the pump flow 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 flow amount, particularly with lower temperatures and increased fl uid viscosities. Settings may need to be
established through correlation study. Consult factory.
• Hardened parts for long life.
• Quiet, modulated response.
• Compact size.
Operating Pressure: 207 bar (3000 psi)
Flow Rate: 7.6 lpm (2.0 gpm) max. regulated; 11.4 lpm (3.0 gpm) max. input. Inlet pressure at ➀ begins to rise over the compensating differential when bypass flow exceeds 7.5 lpm (2 gpm)
Standard Compensator Bias Spring: 6.5 bar (95 psid) differential
Flow Maintenance Setting Range: 0.4 to 1.8 lpm (0.10 to 0.49 gpm) to accuracy of ±15%; 1.9 to 7.5 lpm (0.5 to 2.0 gpm) to accuracy of ±10%
