The Hydraforce 5028221 (5028221) is a solenoid-operated, 4-port, 3-position, direct-acting spool-type screw-in hydraulic cartridge valve designed for robust and efficient hydraulic flow control. The valve features a unique configuration that allows for versatile flow directions depending on the energization of the coils. In its default de-energized state, the SV1047AX model blocks cylinder ports while permitting flow from port 3 to port 1. Energizing coil 1 changes the flow direction from port 3 to port 2 and from port 4 to port 1, whereas activating coil 2 allows flow from port 3 to port 4 and from port 2 to port 1. This valve is particularly suited for applications where work port flows are unequal due to cylinder ratios; it is recommended that higher return flows be directed to port 2. Key features of this model include a continuous-duty rated solenoid and a hardened precision spool and cage which ensure long service life even under demanding conditions. The SV1047AX offers optional coil voltages and terminations, enhancing its adaptability for various electrical systems. It also includes a manual override option, which provides additional operational flexibility. For environments requiring rigorous standards, there are optional waterproof E-Coils rated up to IP69K available, ensuring performance in moisture-intensive conditions. The efficient wet-armature construction of the valve enhances its reliability and performance. All ports on this valve can withstand full pressurization, highlighting its robust design suited for high-pressure applications. Additionally, the cartridges are voltage interchangeable which simplifies maintenance and replacement processes. The unitized, molded coil design along with an industry-common cavity further underscores its utility in diverse hydraulic systems.
