FR12-30F Regulator, Pressure-Compensated (FR12-30F)
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.
Product Operation
The FR12-30F 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 ➁ to ➂The FR12-30F 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.
Product Features
• Hardened parts for long life.
• Quiet, modulated response.
• Cost effective cavity.
