FR50-23 Regulator, Pressure-Compensated, (FR50-23)
A screw-in, cartridge-style, adjustable, pressure-compensated, restrictive-type hydraulic flow regulating valve.
Product Operation
The FR50-23 maintains a constant flow rate out of ➁ regardless of load pressure changes in the circuit downstream of ➁ or upstream of ➀The 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 ➁ to ➀ bypasses the control orifice.
Product Features
• Hardened parts for long life.
• Quiet, modulated response.
• Cost-effective cavity.
