The Hydraforce 5004221 (5004221) is a solenoid-operated, 2-port, normally open, poppet type proportional screw-in hydraulic cartridge valve. This valve is specifically designed for low leakage in load-holding applications, enhancing its suitability for precise fluid control in hydraulic systems. The SP0821 model operates by allowing flow from port 2 to port 1 when de-energized; however, the flow from port 1 to port 2 is significantly restricted under these conditions. As the valve becomes partially energized (refer to the performance curve for details), it starts to throttle the flow from port 2 to port 1. Upon full energization, the valve’s poppet closes completely against the seat, effectively blocking any flow from port 2 to port 1. Conversely, flow from port 1 to port 2 is possible once the solenoid force is overcome. Key features of this model include a continuous-duty rated coil and efficient wet-armature construction which contribute to its robust performance and durability. It also offers optional waterproof E-Coils that are rated up to IP69K, ensuring protection against ingress of dust and high-temperature high-pressure water jets. This makes it particularly useful in environments where moisture or dust exposure is a concern. Additionally, its industry common cavity allows for easy installation and compatibility with existing systems, while its compact size facilitates integration into tighter spaces without compromising on power or efficiency. These characteristics make the Hydraforce 5004221 an excellent choice for a variety of hydraulic applications requiring reliable and controlled operation.
