The Hydraforce EPFR52-S35-0-N-80 (5281170) is a screw-in, cartridge-style, bypass type pressure compensating element designed for high-efficiency hydraulic systems. This valve ensures a constant flow regardless of load pressure changes and is particularly suitable for applications with remote fixed or variable orifices. It operates with a spring-biased spool and includes an internal orifice between ports 2 and 3, which allows the valve to bypass all flow to the tank when the bias spring pressure value plus the pressure rise at no load flow demand is reached. The internal orifice is also pressure compensated to minimize flow loss during load flow demand. This model boasts several features enhancing its functionality and efficiency. It offers multiple functions within a single cavity, maintains low bleed flow across its operating pressure range, and ensures high system efficiency compatible with industry-common cavities. The EPFR52-S35-0-N-80 can handle pressures up to 345 bar (5000 psi) and supports a maximum flow rate of 151 lpm (40 gpm). It exhibits minimal maximum flow loss of about 0.76 lpm (0.20 gpm) between ports 3 and 2 at maximum pressure. Additionally, it accommodates a wide range of temperatures from -40°C to +100°C (-40°F to +212°F) with Buna N seals, making it versatile for various operational environments. The unit weighs approximately 0.28 kg (0.61 lb), ensuring it remains lightweight yet robust enough for demanding applications. It fits within VC12S3 cavities and can be installed using a torque range of 44.7 to 50.2 Nm (33 to 37 ft-lb), allowing for easy integration into existing systems without any orientation restrictions.
