The Hydraforce EPFR58-35-0-N-80 (5281130) is a screw-in, cartridge-style, bypass-type pressure compensating element designed to maintain a constant flow rate regardless of load pressure changes. This valve is particularly effective when paired with either a fixed or variable orifice at a remote location. It operates through a spring-biased spool mechanism and includes an internal orifice between ports 2 and 3. This design allows the valve to bypass all flow to the tank once the bias spring pressure plus any pressure rise at no-load flow demand is reached. The EPFR58-35-0-N-80 is engineered for high efficiency in hydraulic systems, featuring low bleed flow across its operating pressure range which spans up to 345 bar (5000 psi). The maximum flow loss through this component is notably minimal at 0.76 lpm (0.20 gpm) between ports 3 and 2 under maximum pressure. It supports a wide range of operating fluid temperatures from -40°C to +100°C (-40°F to +212°F) with standard Buna N seals, and can handle even broader ranges with alternative seal materials like Fluorocarbon and Polyurethane. This model's versatility is further enhanced by its compatibility with various hydraulic fluids, including mineral-based or synthetic types with lubricating properties, within a viscosity range of 7.4 to 420 cSt. Additionally, it ensures reliability in diverse environmental conditions given its ambient temperature operational range from -40°C to +90°C (-40°F to +194°F). The unit itself weighs approximately 0.1 kg (0.22 lb) and fits into industry-common cavity VC083. Installation specifications for the EPFR58-35-0-N-80 are straightforward, requiring no specific orientation and a torque between 25.8 to 28.5 Nm (19 to 21 ft-lb). For maintenance or replacement needs, seal kits including Buna N, Fluorocarbon, and Polyurethane options are available along with corresponding installation instructions.
