The Sun Hydraulics DNCADZV928 (DNCADZV928) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve features a closed transition between positions, which significantly minimizes oil loss during shifting\u2014crucial for maintaining efficiency in pilot control circuits. The valve operates with a capacity based on port 3 as the inlet and port 1 as the tank; however, while reverse flow is possible through this configuration, optimal performance in this mode is not guaranteed. Rated for up to 5000 psi (350 bar) service, the solenoid tube assembly of this valve is fatigue-rated for robust performance even under high-pressure conditions. It requires no minimum hydraulic pressure to operate effectively, which simplifies integration into various hydraulic setups. Notably, cartridges configured with EPDM seals are specifically designed for systems using phosphate ester fluids; exposure to petroleum-based fluids should be avoided as it can damage the seals. The DNCADZV928 employs a wet armature design where the working fluid surrounds the armature. This design consideration is vital when the coil is energized for extended periods since some fluids may degrade under prolonged heat exposure. The valve offers a variety of coil termination and voltage options to suit diverse operational requirements and environments. Its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in any direction on the tube. This model also incorporates Sun\u2019s floating style construction which helps prevent internal parts binding that might occur due to excessive installation torque or variations in cavity/cartridge machining. With its quick response time of approximately 50 ms and a maximum operating pressure of 5000 psi (350 bar), the DNCADZV928 provides reliable and efficient performance suitable for demanding applications requiring precise directional control of hydraulic flow.
