The Sun Hydraulics DNCADSN224 (DNCADSN224) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic fluid direction control. This direct-acting, balanced spool directional valve ensures closed transitions between positions, significantly minimizing fluid loss during operation shifts. Ideal for use in pilot control circuits where such characteristics are crucial. The DNCADSN224 operates efficiently with a port 3 inlet and port 1 tank configuration, although it allows reverse flow; performance consistency in reverse setups isn't assured. The robust design includes a solenoid tube assembly rated for fatigue at 5000 psi (350 bar), ensuring durability and reliability even under high-pressure conditions. The valve does not require minimum hydraulic pressure to function and is equipped with EPDM seals specifically for phosphate ester fluids; however, exposure to petroleum-based substances should be avoided to prevent seal damage. This model features a wet armature design where the working fluid surrounds the armature. Continuous energization of the coil might lead to fluid breakdown over time due to heat exposure, particularly with water-glycol mixtures which can degrade and form varnishes impacting cartridge functionality. Various coil termination options are available along with voltage choices that include surge protection enhancements. The DNCADSN224's magnetic design enhances solenoid efficiency providing greater actuating force per watt expended which contributes to reliable valve shifting. Coils are interchangeable across other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additional features like IP69K rated coil connector options and weatherized coils enhance environmental protection capabilities. Sun Hydraulics has also incorporated their floating style construction into this model to reduce risks associated with internal part binding due to excessive installation torque or cavity/cartridge machining variations, further ensuring operational reliability and longevity of the valve system.
