A screw-in, cartridge-style, fi xed orifice, pressure-compensated, hydraulic flow regulating valve (restrictive type).
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.
• Hardened parts for long life.
• Quiet, modulated response.
• Compact size.
Operating Pressure: 240 bar (3500 psi)
Flow Settings: 0.4 lpm (0.1 gpm) min., 7.5 lpm (2.0 gpm) max.
Standard Compensator Bias Spring: 5.5 bar (80 psid) differential
Flow Maintenance Setting Range: 0.2 to 1.8 lpm (0.05 to 0.49 gpm) to accuracy of ±15%; 1.9 to 7.5 lpm (0.5 to 2.0 gpm) to accuracy of ±10%
