FLOW CONTROLS
FR16-30F Regulator, Pressure-Compensated
DESCRIPTION
A screw-in, cartridge-style, pressure-compensated, non-adjustable fl ow regulator,
intended for use in fi xed displacement hydraulic circuits requiring partial pump fl ow
diversion on a priority basis.
OPERATION
The FR16-30F maintains a constant fl ow rate from ➂ regardless of load pressure
changes in the system downstream of
➂, or in the bypass leg at ➁.
The valve’s spool maintains a constant differential pressure of 5.5 bar (80 psi) across
a fi xed internal orifi ce, thereby regulating the hydraulic fl ow rate from
➀ to ➂.
The FR16-30F is a priority type regulator, delivering the pump fl ow 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 fl ow amount, particularly with
lower temperatures and increased fl uid viscosities. Settings may need to be
established through correlation study. Consult factory.
FEATURES
• Hardened parts for long life.
• Quiet, modulated response.
