The Hydraforce 5278712 (5278712) is a state-of-the-art EHPR98G38XXX model, distinguished by its role as a direct-acting, spool-type, proportional, pressure reducing relieving valve. This 3rd generation valve is designed as a drop-in, flange-mounted cartridge type that is particularly suited for use with either mineral-based or synthetic hydraulic fluids possessing lubricating properties. The integral coil within the valve underscores its innovative design, focusing on non-serviceability to enhance durability and reliability in demanding environments.
This model boasts a regulated pressure that is directly proportional to the input electrical current across specified pressure ranges. It is equipped with features that promote efficiency and adaptability including an economical drop-in style and various mounting plate options which facilitate easy installation and retrofitting processes. Notably, the valve offers several regulated pressure ranges to accommodate different application needs.
For optimal performance, the standard plunger configuration is recommended for applications facing inlet pressures up to 34 bar (500 psi), where a faster response and increased volume at the control port are necessary. Conversely, for higher pressure applications up to 69 bar (1000 psi) that require decreased volume at the control port, the use of a damped plunger is advised to maintain stability.
Additional features such as quick response time, low leakage rates, and optional screen and top-mounted connector enhancements make the Hydraforce 5278712 an excellent choice for systems requiring precise pressure management with reliable relieving capabilities.
