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 FR16-30F 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 5.5 bar (80 psi) across a fixed internal orifice, thereby regulating the hydraulic flow rate from 1 to 3.
The FR16-30F 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.
