The Sun Hydraulics DLDAZHN912N (DLDAZHN912N) is a high-performance, solenoid-operated 2-way, 2-position cartridge valve designed to control the direction of hydraulic fluid in advanced fluid power systems. This direct-acting, balanced spool directional valve can be configured as either normally open or normally closed, depending on the application requirements. It features a position switch that confirms the valve\u2019s current state, enhancing operational safety and reliability. This model is tailored for systems requiring precise control with a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min). The DLDAZHN912N responds swiftly with typical response times around 50 ms and maintains tight control over leakage with maximum valve leakage specified at 5 in\u00b3/min at 3000 psi. Its robust design includes a fatigue-rated solenoid tube assembly for demanding applications. Notably, the DLDAZHN912N incorporates Sun's floating style construction which minimizes internal part binding caused by excessive installation torque or variations in cavity/cartridge machining. This feature ensures long-term reliability and consistent performance. Additionally, the wet armature design of the solenoid means that while it offers efficient heat management, users should consider fluid compatibility especially when operating continuously or with specific fluid types like water-glycol mixtures. Installation requires specific tools such as a crow's foot wrench due to the position switch configuration which obstructs deep socket wrench use. The unit comes sealed from the factory and is not field serviceable; any required adjustments or servicing must be handled by returning it to Sun Hydraulics to maintain warranty protections. Various coil termination and voltage options are available for this model, allowing customization to meet diverse system requirements effectively.
