The Sun Hydraulics DLDAZCV212N (DLDAZCV212N) 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 requirements. It features an integrated position switch that confirms the valve's return to the spring-biased position, enhancing operational reliability and safety. This model is specifically engineered with a wet armature design, where the working fluid surrounds the armature. This characteristic is crucial for applications where the coil may be energized for extended periods, although users should note that certain fluids may degrade under prolonged heat exposure. The valve operates without requiring a minimum hydraulic pressure, making it versatile across various low and high-pressure systems. The DLDAZCV212N offers robust performance specifications including a maximum operating pressure of 5000 psi (350 bar), and a flow capacity of up to 12 gpm (45 L/min). Its quick response time of approximately 50 ms and maximum valve leakage at 110 SUS (24 cSt) of 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar) make it suitable for applications requiring precise fluid control and minimal leakage. The solenoid tube assembly of this model is fatigue rated for demanding conditions. 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. It also incorporates Sun\u2019s floating style construction which minimizes internal parts binding\u2014a common issue in environments with variable installation torque or machining variations. With its efficient magnetic design yielding high spool actuating force per Watt expended, this valve ensures reliable shifting and performance in critical applications. Note that any adjustments or service must be conducted by returning the unit to the factory to avoid voiding its warranty.
