The Sun Hydraulics DLDAZHN624N (DLDAZHN624N) is a high-performance, solenoid-operated 2-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed to function efficiently in either a normally open or normally closed configuration, depending on the specific application needs. It features a position switch that confirms the valve is in the spring-biased position, enhancing operational safety and reliability. Notably, this model requires an accompanying coil which must be ordered separately. The valve itself is sealed and factory set; thus, it is not serviceable in the field. Any required modifications or servicing must be handled directly by returning it to the factory, ensuring maintenance of warranty conditions due to sensitivity to tampering. The DLDAZHN624N operates with no minimum hydraulic pressure required for its operation and incorporates a wet armature design. This design allows the working fluid to surround the armature which can be significant if the coil remains energized for extended periods\u2014especially when using water-glycol mixtures that may degrade under prolonged exposure to heat. This model offers various coil termination and voltage options, including configurations with or without surge protection. The solenoid\u2019s unique magnetic design ensures high efficiency with greater spool actuating force per watt expended, contributing to reliable valve shifting. The construction also includes Sun's floating style which minimizes potential internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. Technical specifications include a maximum operating pressure of 5000 psi (350 bar), a flow capacity of 12 gpm (45 L/min), and typical response times of 50 ms. It supports switching frequencies up to 15,000 cycles/hr and has been fatigue rated for rigorous use at high pressures. Installation requires specific tools like a crow's foot wrench due to the position switch design that obstructs deep socket wrench use.
