The Hydraforce EPFR16-S35T-0-N-160 (5281154) is a precision-engineered pressure compensating element designed for hydraulic systems requiring consistent flow control despite changing load pressures. This screw-in, cartridge-style valve is primarily utilized with a remote fixed or variable orifice to maintain steady flow. The device features a spring-biased spool valve with an internal orifice between ports 2 and 3, which enables it to bypass all flow to the tank when the bias spring pressure plus no-load flow demand pressure rise is reached. This internal orifice is uniquely pressure compensated to minimize flow loss during load demands. This model boasts multiple functions within a single cavity design, offering high system efficiency and low bleed flow across its operating pressure range, which reaches up to 241 bar (3500 psi). The EPFR16-S35T-0-N-160 can accommodate various bias spring options; however, higher pressures require a tall adapter, and an extra tall adapter is necessary for the 240 psi bias spring option. It operates effectively within a fluid temperature range of -40°C to +100°C (-40°F to +212°F) with Buna N seals and has broader ranges with other seal types. The unit's compatibility with mineral-based or synthetic hydraulic fluids with lubricating properties ensures versatility in application across different hydraulic setups. Its design also supports a wide viscosity range of fluids from 7.4 to 420 cSt while maintaining maximum operating contamination levels as per ISO 4406 standards. Weighing approximately 0.29 kg (0.64 lb), this compact valve integrates seamlessly into existing systems without requiring significant modifications, facilitated by its industry-standard VC16S3 cavity size for installation.
