The Hydraforce 5500400N (5500400N) is a high-performance hydraulic directional element, specifically designed for demanding applications that require reliable load holding or blocking capabilities. This valve is a pilot-to-open, balanced poppet-type model, engineered to provide bidirectional flow control. It operates by blocking flow from ports 1 to 2 in its unpiloted state, ensuring low internal leakage and enhancing system efficiency. Upon receiving a remote pilot signal at port 3, the valve shifts to allow controlled flow between these ports in both directions. A distinctive feature of the 5500400N is its hydraulically balanced poppet, which maintains stability and performance even when ports 1 and 2 are fully pressurized. This design characteristic ensures that the pilot pressure required for actuation remains consistent and unaffected by the pressure conditions at these ports. Additionally, the spring chamber of this valve is vented to port 4, which should be connected to the tank. This connection not only facilitates lubrication of internal components but also influences the pilot pressure needed for shifting the valve; pressure at port 4 adds to the required pilot shift pressure. With zero pressure at port 4, this valve can fully shift with a minimum pilot pressure of 200 psi (approximately 14 bar), showcasing its efficiency in various hydraulic setups. The Hydraforce 5500400N adheres to stringent NFPA T2.6.1 specifications, ensuring reliability and performance with a verification level of 90% and an assurance level of 99%. This makes it an ideal choice for applications where precision and durability are crucial.
