The Hydraforce 5278789 (5278789) is a high-performance hydraulic valve designed for precise fluid control in various applications. Known as the EHPR98G38XXX, this valve is a direct-acting, spool-type, proportional pressure reducing and relieving valve. It is engineered as a 3rd generation Hydraforce drop-in, flange-mounted cartridge type, making it suitable for integration into existing hydraulic systems with minimal modification. This model is specifically designed to work with mineral-based or synthetic hydraulic fluids that have lubricating properties. The EHPR98G38XXX features an integral coil which is essential for its operation but is not serviceable, emphasizing the need for correct installation and maintenance to ensure longevity. The valve's functionality allows the regulated pressure to be directly proportional to the input electrical current within specified pressure ranges. For optimal performance, the standard plunger version of this valve is recommended for applications experiencing inlet pressures up to 34 bar (500 psi). This setup benefits from faster response times and increased volume at the control port. Conversely, for higher pressure applications up to 69 bar (1000 psi) where reduced volume at the control port is observed, using the damped plunger variant is advisable to maintain stability and performance. Additional features of the EHPR98G38XXX include economical drop-in style installation, multiple mounting plate options, several regulated pressure ranges available for different requirements, and a quick response time. It also offers low leakage characteristics and retrofit options for previous models like the EHPR98T38. A top-mounted connector and optional screen further enhance its usability and integration ease in complex hydraulic setups.
