The Sun Hydraulics DLDAZHV612 (DLDAZHV612) is a high-performance, solenoid-operated 2-way, 2-position cartridge valve, designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve can be configured as normally open or normally closed based on the needs of the system. It features a position switch that confirms the valve's status in its spring-biased position, enhancing operational reliability and safety. This model is engineered with a wet armature design where the working fluid surrounds the armature which is exposed to heat when the coil is energized. Such a setup demands consideration of fluid characteristics as prolonged exposure to high temperatures can degrade certain types of fluids like water-glycol mixtures. The solenoid tube assembly of this valve is fatigue rated for service up to 5000 psi (350 bar), making it suitable for high-pressure applications. Notably, this cartridge utilizes Sun\u2019s unique magnetic design that ensures high efficiency and effective spool actuating force per watt expended, resulting in reliable valve shifting. Additionally, it incorporates Sun\u2019s floating style construction that minimizes internal parts binding which could occur due to excessive installation torque or variations in cavity/cartridge machining. The DLDAZHV612 supports a variety of coil termination and voltage options and offers surge protection configurations. Its maximum operating pressure stands at 5000 psi (350 bar), with a flow capacity up to 12 gpm (45 L/min). The valve's rapid response time of typically 50 ms and maximum leakage at 110 SUS 24 cSt being limited to 5 in\u00b3/min at 3000 psi ensures efficient operation. Installation requires specific tools such as a crow's foot wrench due to the presence of the position switch which obstructs deep socket wrench usage. This product comes sealed and factory set; thus, it is not field serviceable. Any necessary adjustments or servicing must be performed by returning it to the factory to maintain warranty conditions and ensure optimal performance.
