The Sun Hydraulics DLDAZHN228 (DLDAZHN228) is a high-performance, solenoid-operated 2-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve can be configured as normally open or normally closed based on application needs. It features a position switch that confirms the valve\u2019s status, enhancing operational safety and reliability. Key specifications include a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min). The valve exhibits rapid response times typically around 50 ms and maintains tight control over leakage, with maximum valve leakage at 110 SUS (24 cSt) being only 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). The robust design includes a fatigue-rated solenoid tube assembly suitable for continuous operation at high pressures. Engineered for durability and performance, the DLDAZHN228 utilizes a wet armature design where the working fluid surrounds the armature. This setup requires consideration of fluid characteristics as prolonged exposure to heat can degrade certain types of fluids. The unit's unique magnetic configuration results in efficient solenoid operation with high spool actuating force per watt expended. Additionally, it incorporates Sun\u2019s floating style construction to minimize internal parts binding due to installation torque or cavity/cartridge machining variations. Installation requirements specify using a crow\u2019s foot wrench due to the position switch configuration which prevents the use of deep socket wrenches. Torque specifications range from 30 \u2013 35 lbf ft (41 \u2013 47 Nm). The model weighs approximately .50 lb (0.25 kg) and offers various coil termination and voltage options including models with surge protection. Note that any adjustments or service must be conducted by returning the cartridge to the factory as it is not field serviceable; tampering with the unit voids its warranty.
