FR08-20F Regulator, Pressure-Compensated (FR08-20F)
A screw-in, cartridge-style, fi xed orifice, pressure-compensated, hydraulic flow regulating valve (restrictive type).
Product Operation
The FR08-20F maintains a constant flow rate out of ➁ regardless of load pressure changes in the circuit downstream of ➁The fi xed control orifice is factory preset to customer flow specifi cation. 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 240 bar (110 to 3500 psid). Reverse flow
(➁ to ➀) returns through the control orifice and is non-compensated.
Product Features
• Hardened parts for long life.
• Quiet, modulated response.
• Compact size.
