The Sun Hydraulics DNDAXSN624N (DNDAXSN624N) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is built with a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), ensuring reliable performance in high-pressure applications. It operates independently of hydraulic pressure, making it versatile for various systems. The design includes multiple manual override options, although models with weatherized coils are not compatible with this feature. For models featuring the D or L control, the manual override's detent mechanism supports temporary actuation, lasting approximately 7,000 cycles. This cartridge valve uses EPDM seals suitable for phosphate ester fluids but should avoid petroleum-based fluids to prevent seal damage. Its wet armature design allows working fluid to surround the armature and manage heat from the coil; however, prolonged coil energization can degrade certain fluids like water-glycol mixtures over time. The solenoid's magnetic design enhances efficiency by providing high spool actuating force per watt of power used. The valve features interchangeable coils within Sun Series 1 products and offers various coil termination and voltage options with optional surge protection. Coil connector options provide protection ratings up to IP69K for increased environmental resilience. The floating style construction minimizes internal component binding risks due to excessive torque or machining variations. In terms of specifications, the valve fits into cavity T-31A and belongs to Series 1 with a capacity of 10 gpm (40 L/min). It has a typical response time of 50 ms and maximum leakage at 110 SUS (24 cSt) of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). It can endure switching frequencies up to 15,000 cycles/hr and requires a manual override force of approximately 5 lbs/1000 psi (33 N/100 bar) at Port 1. The valve weighs around .60 lb (.30 kg) and includes Viton seal kits for both cartridge and coil components.
