The Sun Hydraulics DLDAZHV228 (DLDAZHV228) is a high-performance, solenoid-operated 2-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is engineered for precision and reliability in hydraulic systems. It is available in both normally open or normally closed configurations to suit various application requirements. The valve features a position switch that confirms its status, ensuring operational accuracy and safety. Designed with a robust solenoid tube assembly rated for up to 5000 psi (350 bar), this valve guarantees durability even under intense operating conditions. It operates without the need for minimum hydraulic pressure, enhancing its versatility across different hydraulic applications. The wet armature design allows the working fluid to surround the armature, which can be critical in applications where the coil may be energized for extended periods. This model also incorporates Sun's unique floating style construction which minimizes internal parts binding, a common issue caused by excessive installation torque or cavity/cartridge machining variations. Installation of the DLDAZHV228 requires specific tools such as a crow's foot wrench due to the position switch design that precludes the use of a deep socket wrench. The valve supports a wide range of coil termination and voltage options, providing flexibility for system integration and ensuring compatibility with various power supplies and operational environments. Its efficient magnetic design results in high spool actuating force per watt expended, leading to reliable valve shifting even under challenging conditions. With a maximum capacity of 12 gpm (45 L/min) and quick response time typically around 50 ms, the DLDAZHV228 enhances system responsiveness and efficiency. Its compact size (.50 lb/0.25 kg) and specific seal kit options (Viton: 990413006) make it an ideal choice for streamlined yet powerful hydraulic systems requiring precise control and long-term reliability.
