The Hydraforce 5281145 (5281145) is a precision-engineered pressure compensating element designed for advanced fluid power applications. This screw-in, cartridge-style valve, identified as EPFR50S35 in technical documents, functions primarily as a bypass type pressure compensating element suitable for pairing with both fixed and variable orifices. Its primary role is to maintain a consistent flow rate despite changes in load pressure, enhancing system responsiveness and stability. The operation of the 5281145 is governed by a spring-biased spool mechanism which includes a small internal orifice between ports 2 and 3. This design feature allows the valve to bypass all flow back to the tank when the bias spring pressure plus any pressure rise occurs during periods of no load flow demand. Furthermore, the orifice is adeptly pressure compensated to minimize flow loss even during high load demands, ensuring efficient system performance. Among its notable features are its ability to perform multiple functions within a single cavity, achieving low bleed flow across the entire operating pressure range which contributes significantly to high system efficiency. Additionally, it utilizes an industry-common cavity which facilitates compatibility and interchangeability with various system designs. The Hydraforce 5281145 is crafted to offer reliable control in hydraulic systems, making it an essential component for optimizing machine operations across numerous applications.
