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.
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.
Hardened parts for long life.
Quiet, modulated response.
