FR08-20F Valve

SYMBOL:
FR08-20F Valve symbol

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

OPERATION
The FR08-20F 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
• Hardened parts for long life.
• Quiet, modulated response.
• Compact, industry-common cavity.
