DESCRIPTION
A screw-in, cartridge-style, adjustable, pressure-compensated, restrictive-type, hydraulic flow regulating valve for operation up to 345 bar (5000 psi).
OPERATION
The FR50-28 maintains a constant flow rate out of port 2 regardless of load pressure changes in the circuit downstream of 2, or upstream of 1.
The regulated flow increases from closed to fully open with counter-clockwise rotation of the adjustment screw. The valve will maintain the set flow regardless of pressure variations on the regulated or inlet port. Reverse flow from 2 to 1 bypasses the control orifice.
FEATURES
• Hardened parts for long life.
• Quiet, modulated response.
• Industry-common cavity.
