The Hydraforce 5028305 (5028305) is a solenoid-operated, 4-port, 3-position, direct-acting spool type screw-in hydraulic cartridge valve designed for robust and versatile performance in hydraulic systems. This model features a unique configuration that allows it to block all ports when de-energized, ensuring a fail-safe operation. When coil 1 is energized, the valve facilitates flow from port 3 to port 4 and from port 2 to port 1, whereas energizing coil 2 shifts the flow from port 3 to port 2 and from port 4 to port 1. This functionality makes it particularly suitable for applications where work port flows are unequal due to cylinder ratios; it is recommended that the higher return flow be directed to port 2. The valve boasts several advanced features aimed at enhancing its reliability and longevity. It comes with continuous-duty rated solenoids and a hardened precision spool and cage which ensure long life even under demanding conditions. The optional coil voltages and terminations offer flexibility for various operational requirements, while the manual override option provides additional control during system troubleshooting or maintenance. For environments requiring rigorous standards of durability, there are optional waterproof E-Coils rated up to IP69K available. Efficient wet-armature construction minimizes power loss and maximizes hydraulic efficiency. The design also supports full pressurization of all ports, adding to its versatility across different hydraulic applications. Furthermore, its cartridges are voltage interchangeable which simplifies maintenance and stock management. The unitized, molded coil design enhances durability and performance consistency. Its industry common cavity feature allows for easy integration or replacement in established systems without the need for extensive modifications.
