The Hydraforce 5278616 (5278616) is a state-of-the-art hydraulic component designed for sophisticated fluid power applications. This model, known as the EHPR98G35, is a third-generation, direct-acting, spool-type, proportional pressure reducing/relieving valve. It stands out in the HydraForce line for its compact design and efficient performance, making it ideal for integration into various hydraulic systems with minimal spatial requirements. This valve operates effectively with both mineral-based and synthetic hydraulic fluids that possess lubricating properties. The EHPR98G35 features an integral coil which is crucial to its operation but is not serviceable, emphasizing the need for precision in handling and installation. The regulated pressure of this valve correlates directly with the input electrical current within specified pressure ranges, ensuring precise control over hydraulic system operations. Key attributes of the EHPR98G35 include its economical drop-in style which facilitates easy installation and replacement. It also offers options such as a mounting plate for enhanced stability and compatibility with existing systems. This model serves as a retrofit option for the EHPR98T35, providing versatility in upgrading older systems or replacing parts without extensive modifications. Additional practical features include a quick response time to changes in input signals, an inlet screen that protects against particulate contamination, multiple pressure options to suit varying operational requirements, and a top-mounted connector for simplified electrical integration. Furthermore, it boasts low leakage characteristics which enhance the overall efficiency and reliability of the hydraulic system it is part of.
