The Sun Hydraulics DNCADZV228 (DNCADZV228) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve features a closed transition between positions, minimizing oil loss during shifting which is crucial in pilot control circuits. It operates efficiently with a capacity based on port 3 as the inlet and port 1 as the tank, though reverse flow is possible but not recommended for optimal performance. The DNCADZV228 valve boasts a robust design with its solenoid tube assembly being fatigue rated for up to 5000 psi (350 bar) service. This makes it suitable for demanding applications requiring reliable and continuous operation. The valve does not require minimum hydraulic pressure to function and comes with EPDM seals configured specifically for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. A notable feature of this model is its wet armature design where the working fluid surrounds the armature, potentially affecting fluid integrity under prolonged energization due to heat exposure. The valve offers various coil termination and voltage options, including models with surge protection, enhancing its versatility across different operational setups. Additionally, coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. For environmental durability, weatherized coils and kits are available to provide enhanced protection against harsh conditions. The DNCADZV228 also incorporates Sun\u2019s floating style construction which minimizes internal parts binding\u2014a common issue due to excessive installation torque or cavity/cartridge machining variations. With an array of features designed to ensure reliability and performance under various conditions, this valve is an excellent choice for sophisticated hydraulic systems requiring precise control and durability.
