The Hydraforce FR12-20F-0-N-/8.50 (5422300.8.50) is a screw-in, cartridge-style, fixed orifice, pressure compensated hydraulic flow regulator valve of the restrictive type. This model is designed to maintain a constant flow rate from port 1 to port 2 irrespective of load pressure changes, with reverse flow returning through the control orifice in a non-compensated manner. The valve features hardened parts that ensure longevity and durability under varying operational conditions. It offers a quiet and modulated response, which makes it suitable for applications requiring precise control over fluid handling without noise disturbances. The FR12-20F-0-N-/8.50 has a pressure rating of up to 240 bar (3500 psi) and can handle flow rates ranging from 4.0 to 55 lpm (1.0 to 14.5 gpm). It operates efficiently within a fluid temperature range of -40 to +100°C (-40 to +212°F) with Buna N seals, and an extended range up to -26 to +204°C (-15 to +400°F) with fluorocarbon seals. Furthermore, it supports mineral-based or synthetic hydraulic fluids with lubricating properties within a viscosity range of 7.4 to 420 cSt and can tolerate maximum operating contamination levels as specified by ISO 4406:18/16/13. This model is lightweight at only 0.25 kg (0.56 lb) and has an internal wetted surface area of approximately 162 cm² (25 in²). Installation specifications include a VC122 cavity requirement and cartridge installation torque between 45 to 50 Nm (33 to 37 ft-lb), with no orientation restrictions during mounting, providing flexibility in system design configurations.
