The Sun Hydraulics DLDAZCN228 (DLDAZCN228) is a high-performance solenoid-operated 2-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve can be configured as either normally open or normally closed based on application needs. Featuring a unique magnetic design, the solenoid in this model provides efficient operation with a high spool actuating force per watt expended, ensuring reliable valve shifting even under demanding conditions. The DLDAZCN228 incorporates Sun Hydraulics' floating style construction which minimizes the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This design enhances the overall durability and performance stability of the valve. It is equipped with a CE-approved position switch that confirms the valve's position when it is in the spring-biased position, adding an extra layer of operational security and user feedback. This model has a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 12 gpm (45 L/min). The solenoid tube assembly is fatigue rated for 5000 psi service, making it suitable for high-pressure applications. It features quick response times typically around 50 ms and allows up to 15,000 switching cycles per hour. The wet armature design means that the working fluid surrounds the armature; however, users should consider fluid characteristics as some may degrade at higher temperatures. Installation requires specific tools such as a crow's foot wrench due to the position switch configuration which prevents the use of a deep socket wrench. The valve's hex size is 7/8 in (22.2 mm) and it should be installed with a torque between 30 \u2013 35 lbf ft (41 \u2013 47 Nm). The overall weight of this model is approximately 0.50 lb (0.25 kg). This cartridge system is not field serviceable and must be returned to the factory for any servicing or modifications needed to ensure warranty compliance and maintain operational integrity.
