The Hydraforce 5500500 (5500500) is a high-performance hydraulic directional element featuring a bidirectional, pilot-to-close, balanced poppet design. This cartridge-style valve is engineered primarily to serve as a load holding or blocking valve in hydraulic systems where minimal internal leakage is crucial. It operates effectively by allowing flow from ports 1 to 2 in both directions when unpiloted. Upon receiving a remote pilot signal at port 4, the valve shifts to block flow between these ports bidirectionally. The unique construction includes a spring chamber vented to port 3, which must be connected to the tank. This connection not only aids in lubricating internal components but also influences the pilot pressure needed for shifting the valve, as pressure at port 3 adds directly to this requirement. The hydraulically balanced poppet ensures that full pressurization of ports 1 and 2 does not impact the pilot pressure necessary for actuation. For optimal functionality, with zero pressure at port 3, the valve requires a minimum pilot pressure of 200 psi (14 bar) to fully shift. Designed with robustness in mind, this valve adheres to NFPA specification T2.6.1 standards and undergoes rigorous testing under HyPerformance protocols, achieving a verification level of 90% and an assurance level of 99%. This ensures high reliability and performance consistency in demanding hydraulic applications. The Hydraforce 5500500 is ideal for systems requiring precise control over fluid handling and direction within their operational mechanisms.
