FR12-23 Valve

SYMBOL:
FR12-23 Valve symbol

DESCRIPTION
A screw-in, cartridge-style, adjustable orifice, pressure-compensated, restrictive-type,
hydraulic flow regulating valve.

OPERATION
The FR12-23 maintains a constant flow rate out of port 2 regardless of load pressure changes
in the circuit downstream of port 2, or upstream of port 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 (2 to 1) bypasses the control orifice.

FEATURES
• Hardened parts for long life.
• Quiet, modulated response.
• Cost-effective cavity.
