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 FR12-30F 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 FR12-30F 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. Cost-effective cavity.
