The Hydraforce 5278718 (5278718) is a state-of-the-art hydraulic component specifically designed for advanced fluid power applications. This EHPR98G38XXX model is a direct-acting, spool-type, proportional, pressure reducing relieving valve that stands out due to its robust construction and versatile performance characteristics. It is engineered as a 3rd generation Hydraforce drop-in, flange-mounted cartridge type valve, suitable for systems using mineral-based or synthetic hydraulic fluids with lubricating properties.
This model incorporates an integral coil which is central to its operation but not serviceable, ensuring a compact and durable design. The regulated pressure of this valve is directly proportional to the input electrical current within specified pressure ranges. It offers quick response times and low leakage, making it highly efficient in dynamic system environments.
The EHPR98G38XXX comes with several mounting and pressure range options, enhancing its adaptability for various retrofitting scenarios. It includes features like an economical drop-in style for ease of installation, a mounting plate option for secure attachment, and a top-mounted connector for simplified electrical integration. The standard plunger configuration is recommended for applications with inlet pressures up to 34 bar (500 psi), promoting faster response times and increased control port volume. Conversely, the damped plunger variant is advisable for higher-pressure applications up to 69 bar (1000 psi), where decreased volume at the control port is typical.
Overall, this Hydraforce valve model provides effective pressure management in hydraulic systems requiring precise control over fluid dynamics while maintaining stability and operational reliability under varying conditions.
