The Hydraforce 5500400 (5500400) is a high-performance hydraulic directional element, specifically designed for robust applications requiring a reliable load holding or blocking valve. It features a bidirectional, pilot-to-open, balanced poppet design and is constructed as a screw-in, cartridge-style valve. This model excels in its low internal leakage capabilities and its operation is straightforward: in the unpiloted state, it effectively blocks flow from ports 1 to 2 in both directions. Upon receiving a remote pilot signal at port 3, the valve shifts to permit flow between these ports bidirectionally. A key aspect of the HPC42J48's design is its vented spring chamber connected to port 4, which should ideally be linked to the tank. This connection aids in lubricating internal components and influences the pilot pressure needed for shifting the valve – an essential consideration for accurate operation. The balanced poppet ensures that full pressurization of ports 1 and 2 does not impact the required pilot pressure for activation. Notably, with zero pressure at port 4, the valve can fully shift with a minimum pilot pressure of 200 psi (14 bar). Moreover, this model adheres to rigorous industry standards as evidenced by its testing according to NFPA specification T2.6.1, where all HyPerformance valves are verified at a level of 90% and assured at 99%. This ensures high reliability and performance consistency suitable for various hydraulic applications demanding precise control with minimal leakage.
