The Sun Hydraulics DLDAZHV912 (DLDAZHV912) is a high-performance, solenoid-operated 2-way, 2-position cartridge valve designed for precise hydraulic fluid direction control. This direct-acting, balanced spool directional valve can be configured as normally open or normally closed based on application needs. It features a position switch that confirms the valve's presence in the spring-biased position, enhancing operational safety and reliability. The DLDAZHV912 is engineered to operate without minimum hydraulic pressure, making it versatile for various fluid power applications. It utilizes a wet armature design where the working fluid surrounds the armature, which is crucial in scenarios where the coil may be energized for extended periods. Users should note that certain fluids like water-glycol mixtures might degrade at high temperatures influenced by prolonged coil energization. This model boasts a robust solenoid with a unique magnetic design that provides efficient power usage and strong spool actuating force, ensuring reliable valve shifting even under demanding conditions. The Sun floating style construction incorporated into the DLDAZHV912 minimizes internal parts binding, which can occur due to excessive installation torque or cavity-cartridge machining variations. Key specifications include a maximum operating pressure of 5000 psi (350 bar), a flow capacity of up to 12 gpm (45 L/min), and a fast response time typically around 50 ms. The valve is designed with durability in mind, being fatigue rated for intense 5000 psi service and capable of handling switching frequencies up to 15000 cycles per hour. For installation, specific tools such as a crow's foot wrench are required due to the position switch design that obstructs deep socket wrench use. It is important to adhere strictly to recommended installation torques to avoid compromising the sealed unit integrity and warranty conditions. This cartridge valve is factory set and sealed; thus, it is not serviceable in the field and must be returned to the factory for any modifications or servicing needs.
