The Hydraforce 5278159 (5278159) is a high-performance, direct-acting, spool-type, proportional, pressure reducing and relieving valve designed for robust hydraulic system applications. This model, EHPR0833X, enables precise control over hydraulic pressure by varying the input electrical current to the valve. It facilitates free flow from port 1 to port 3 when the coil is not energized. Upon energizing the coil, a connection between port 1 and port 2 is established, allowing for controlled pressure adjustment. As the electrical current to the coil increases, so does the reduced pressure in a proportional manner. An essential feature of this valve is its ability to relieve excess pressure from port 1 to port 3 if the pressure exceeds a set threshold influenced by the coil's current. This safety mechanism ensures optimal operation under varying pressures without compromising system integrity. The EHPR0833X also includes a manual override function that engages after 2¼ turns, building up pressure at approximately 11.7 bar (170 psi) per turn, offering an additional layer of control in manual or emergency scenarios. This valve is compatible with both 12 and 24-volt coils and can be optionally equipped with waterproof E-Coils rated up to IP69K for enhanced durability against harsh environmental conditions. Its industry-common cavity design allows for straightforward integration into existing hydraulic systems without requiring extensive modifications. The optional manual override further enhances its utility by providing an alternative operation mode under specific conditions.
