FR50-20F Valve

SYMBOL:
FR50-20F Valve symbol

DESCRIPTION
A screw-in, cartridge-style, fixed orifice, pressure-compensated, hydraulic flow regulating valve
(restrictive type) for operation up to 345 bar (5000 psi).

OPERATION
The FR50-20F maintains a constant flow rate out of port 2 regardless of load pressure changes
in the circuit downstream of port 2.
The fixed control orifice is factory preset to customer flow specification. The valve begins to
respond to load changes when the flow through the valve creates a pressure differential across
the control orifice greater than 5.5 bar (80 psid), with accurate flow maintenance from 7.6 to
345 bar (110 to 5000 psid). Reverse flow (2 to 1) returns through the control orifice and is non-
compensated.

FEATURES
• Hardened parts for long life.
• Quiet, modulated response.
• Industry-common cavity.
