The Hydraforce FR12-20F-0-N-/4.50 (5422300.4.50) is a screw-in, cartridge-style hydraulic flow regulator valve designed for precise fluid control in hydraulic systems. This fixed orifice, pressure-compensated valve ensures a consistent flow rate from port 1 to port 2 regardless of load pressure changes, which is crucial for maintaining the performance stability of hydraulic circuits. The valve allows reverse flow through the control orifice, although this flow is non-compensated. Constructed with hardened parts, the FR12-20F-0-N-/4.50 offers durability and a long service life while providing a quiet and modulated response to changes in system conditions. It is engineered for use with mineral-based or synthetic hydraulic fluids that have lubricating properties and can operate within a fluid viscosity range of 7.4 to 420 cSt. The valve's operating parameters include a pressure rating up to 3500 psi (240 bar) and a flow rating ranging from 1.0 to 14.5 gpm (4.0 to 55 lpm). It supports operating fluid temperatures from -40°C to +100°C (-40°F to +212°F) with Buna N seals and from -26°C to +204°C (-15°F to +400°F) with fluorocarbon seals, ensuring versatility across various environmental conditions. This model adheres strictly to contamination levels specified by ISO 4406 standards (18/16/13), ensuring reliability and protection against particulate interference in critical applications. Weighing approximately 0.25 kg (0.56 lb), its compact design fits easily into system configurations using VC122 cavities without orientation restrictions during installation, facilitating ease of use across diverse mechanical setups and applications.
