The Sun Hydraulics DNDAXCV912N (DNDAXCV912N) is a solenoid-operated, 4-way, 2-position cartridge valve that features a direct-acting, balanced spool directional design. This valve is engineered for high performance with a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar) service. It operates without the need for minimum hydraulic pressure, making it versatile in various applications. The valve offers several manual override options, including models with temporary actuation detent mechanisms and a mechanical life expectancy of approximately 7,000 cycles. Notably, cartridges with EPDM seals are intended for systems utilizing phosphate ester fluids, as exposure to petroleum-based substances can damage the seals. The DNDAXCV912N incorporates a wet armature design where the working fluid surrounds the armature and absorbs heat generated by the coil. This feature is crucial in long-term coil energization scenarios as certain fluids may degrade under prolonged exposure to elevated temperatures. The valve supports various coil termination and voltage configurations, some offering surge protection and IP69K-rated connectors for enhanced environmental resilience. This model boasts an efficient magnetic solenoid design that delivers high spool actuating force per watt consumed, ensuring reliable operation. Coils are interchangeable with other Sun Series 1 products and can be mounted bidirectionally on the tube. The valve's construction minimizes internal part binding risks due to installation torque or machining variations. With a capacity of 10 gpm (40 L/min) and maximum operating pressure of 5000 psi (350 bar), this cartridge is ideal for applications requiring rapid response times\u2014approximately 50 ms\u2014and high switching frequency of up to 15,000 cycles per hour. The unit requires manual override force of about 5 lbs/1000 psi and features a stroke length of .10 inches (2.5 mm). For optimal maintenance and performance, Viton seal kits are available for both the cartridge and coil components.
