The Hydraforce 5278708 (5278708) is a high-performance EHPR98G38XXX valve designed for precise hydraulic control. This direct-acting, spool-type, proportional pressure reducing relieving valve is engineered for third-generation applications and features a robust design suitable for both mineral-based and synthetic hydraulic fluids with lubricating properties. It integrates a non-serviceable coil that modulates regulated pressure in response to varying electrical current inputs across specified pressure ranges.
This flange-mounted, cartridge type valve offers multiple configurations to suit varying application needs, including options for mounting plates and top-mounted connectors which enhance its adaptability for retrofitting purposes. The standard plunger variant is optimal for systems requiring quick response times and increased control port volume at inlet pressures up to 34 bar (500 psi). For higher-pressure applications up to 69 bar (1000 psi) where reduced volume at the control port is necessary, the damped plunger version is recommended to maintain stability.
Key features of the Hydraforce 5278708 include its economical drop-in style which facilitates easy installation and maintenance, several regulated pressure ranges that provide flexibility in application use, and a low leakage design that ensures efficient operation. Additionally, it offers quick response times and an optional screen feature to enhance operational reliability. This valve is particularly suited for advanced hydraulic systems requiring precise pressure modulation under varying operational conditions.
