The Sun Hydraulics DMDAZRV824 (Material Number DMDAZRV824) is a solenoid-operated, 3-way, 2-position cartridge valve designed for high-efficiency hydraulic applications. This direct-acting, balanced spool directional valve features a closed transition between positions, significantly minimizing oil loss during shifting\u2014a crucial feature in pilot control circuits. The inclusion of a position switch confirms the valve's status in the spring-biased position, enhancing operational safety and reliability. This cartridge must be used with a specifically ordered coil and is delivered as a sealed unit, not serviceable in the field. Any required modifications or servicing must be performed at the factory to maintain warranty conditions. The design includes a CE-approved position switch, and installation requires specific tools like a crow\u2019s foot wrench due to the position switch design which obstructs the use of a deep socket wrench. Engineered for robust performance, the solenoid tube assembly of this valve is fatigue rated for 5000 psi (350 bar) service. It operates without needing a minimum hydraulic pressure and uses EPDM seals suitable for systems with phosphate ester fluids; however, these seals are susceptible to damage from petroleum-based substances. The wet armature design means that the working fluid surrounds the armature which could lead to fluid degradation if exposed to heat over prolonged periods. The Sun Hydraulics DMDAZRV824 offers versatile configuration options in coil termination and voltage settings, including models with surge protection. Its magnetic design ensures high efficiency with significant spool actuating force per watt expended, ensuring reliable valve shifting under various conditions. Additionally, it incorporates Sun\u2019s floating style construction to reduce internal part binding risks due to installation torque or machining variations of cavity/cartridge. With its comprehensive capabilities and robust design, this valve is an essential component for advanced hydraulic systems requiring precise control and reliability.
