FR12-30F Valve

SYMBOL:
FR12-30F Valve symbol

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.
