The Sun Hydraulics DLDAZHV812N (DLDAZHV812N) is a high-performance, solenoid-operated 2-way, 2-position cartridge valve designed for precise fluid control in hydraulic systems. This direct-acting, balanced spool directional valve can be configured as normally open or normally closed, depending on the application requirements. It features a position switch that confirms the valve is in the spring-biased position, enhancing operational safety and reliability. The DLDAZHV812N operates without minimum hydraulic pressure and incorporates a wet armature design where the working fluid surrounds the armature. This setup is particularly sensitive to prolonged coil energization which may lead to fluid breakdown at high temperatures, affecting performance. The valve's robust solenoid tube assembly is fatigue rated for service up to 5000 psi (350 bar), ensuring durability even under strenuous conditions. With a maximum flow capacity of 12 gpm (45 L/min) and rapid response time of approximately 50 ms, this valve is capable of handling significant hydraulic flow efficiently. The maximum operating pressure also stands at 5000 psi (350 bar), suitable for high-pressure applications. Additionally, it offers various coil termination and voltage options including models with surge protection to meet diverse operational requirements. This unit's construction utilizes Sun\u2019s floating style design which minimizes internal part binding due to installation torque or machining variations in the cavity/cartridge setup. The specific installation requires a crow\u2019s foot wrench due to the position switch configuration that prevents deep socket wrench use. Notably, this cartridge must be ordered with a coil and is not field serviceable; any required modifications or servicing must be conducted at the factory to avoid warranty violations.
