The Hydraforce EPFR52-S35T-0-N-240 (5281181) is a high-performance, screw-in, cartridge-style, bypass type pressure compensating element designed for hydraulic systems requiring consistent flow control despite varying load pressures. This model is particularly effective when paired with remote fixed or variable orifices to maintain a steady flow rate. The EPFR52-S35T-0-N-240 features a spring-biased spool valve with an internal orifice between ports 2 and 3. This design allows the valve to bypass all flow to the tank when the bias spring pressure plus any pressure rise at no-load flow demand is reached. The internal orifice of this model is pressure compensated, which minimizes flow loss during load demands, thus enhancing system efficiency. It operates within a pressure rating of up to 345 bar (5000 psi) and can handle flow rates up to 151 liters per minute (40 gpm). The EPFR52-S35T-0-N-240 has been engineered for low bleed flow across its operating pressure range and incorporates multiple functions within a single cavity. This unit's robust design allows it to operate in fluid temperatures ranging from -40°C to +100°C with Buna N seals, -26°C to +204°C with fluorocarbon seals, and -54°C to +107°C with polyurethane seals. It supports mineral-based or synthetic hydraulic fluids with lubricating properties within a viscosity range of 7.4 to 420 cSt. The maximum operating contamination level is rated at 20/18/14 per ISO 4406. Weighing approximately 0.28 kg (0.61 lb) in its standard configuration and slightly more with the tall adaptor option, the EPFR52-S35T-0-N-240 fits VC12S3 cavity types and can be installed using a torque range of 44.7 to 50.2 Nm (33 to 37 ft-lb). There are no orientation restrictions during installation, making it versatile for various hydraulic system setups.
