The Hydraforce 5281170P (5281170P) is a high-performance, screw-in cartridge style bypass type pressure compensating element designed for advanced hydraulic flow control. The model EPFR52S35, as part of its design, incorporates a spring-biased spool valve with an internal orifice between ports 2 and 3. This configuration allows the valve to bypass all flow to the tank when the bias spring pressure value plus any pressure rise occurs at no load flow demand. Importantly, it features a pressure-compensated orifice that minimizes flow loss during load demand, ensuring efficient operation across varying load pressures. This product boasts multiple functions within a single cavity design, which simplifies installation and maintenance while optimizing system integration. Its low bleed flow feature throughout the operating pressure range enhances system efficiency significantly. Furthermore, the EPFR52S35 uses an industry-common cavity which facilitates compatibility and interchangeability with existing hydraulic systems. This combination of features makes the Hydraforce 5281170P ideal for applications requiring precise flow control in response to changes in load pressure, thereby ensuring consistent performance and reliability in hydraulic systems.
