The Hydraforce 5003463 (5003463) is a solenoid-operated, 2-port, normally open, poppet-type proportional hydraulic cartridge valve. This valve is specifically designed for low leakage in load-holding applications, making it highly suitable for systems requiring precise control of fluid handling. When the SP0821 model is de-energized, it facilitates flow from port 2 to port 1, while flow from port 1 to port 2 is significantly restricted. This feature ensures stability and reliability in maintaining load positions when the valve is not powered. As the valve becomes partially energized, as indicated by its performance curve, it begins to throttle the flow from port 2 to port 1. Full energization results in the valve’s poppet closing tightly against the seat, effectively blocking flow from port 2 to port 1. This complete closure provides robust sealing capabilities essential for preventing fluid loss and maintaining system integrity under various operational conditions. Additionally, this model features a continuous-duty rated coil and efficient wet-armature construction which contribute to its durability and consistent performance. The optional waterproof E-Coils are rated up to IP69K, offering enhanced protection against dust and high-pressure water ingress, thus ensuring functionality in harsh environments. Its industry common cavity design allows for easy integration or replacement within existing hydraulic systems without extensive modifications. The compact size of the Hydraforce 5003463 further aids in its versatility and ease of installation across a broad range of equipment applications requiring precise hydraulic control.
