FR04-20F Valve SYMBOL:
FR04-20F Valve symbol
DESCRIPTION
A screw-in, cartridge-style, fixed orifice, pressure-compensated, hydraulic flow
regulating valve (restrictive type).

OPERATION
The FR04-20F maintains a constant flow rate from port 1 to port 2 regardless of
load pressure changes. Reverse flow returns through the control orifice and is
non-compensated.

FEATURES
• Choice of several flow settings available.
• Hardened parts for long life.
• Quiet, modulated response.
• Compact size.
