The Sun Hydraulics DNDAXSV924N (DNDAXSV924N) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. It is engineered to operate without the need for minimum hydraulic pressure and can withstand service pressures up to 5000 psi (350 bar), thanks to its fatigue-rated solenoid tube assembly. This valve features several manual override options, although these are not compatible with weatherized coils. When equipped with D or L controls, the manual override's detent mechanism is intended for temporary actuation, with an estimated mechanical life of approximately 7,000 cycles. The cartridge is optimized for use in systems utilizing phosphate ester fluids when equipped with EPDM seals; exposure to petroleum-based fluids can damage these seals. The valve utilizes a wet armature design which allows working fluid to surround the armature and dissipate heat generated by the coil\u2014caution is advised as some fluids may break down over time due to heat exposure. A variety of coil termination and voltage configurations are available, including options with surge protection. The solenoid's magnetic design enhances efficiency by providing high actuating force per watt expended, ensuring reliable operation. Coils are interchangeable across Sun Series 1 products and can be mounted in either direction on the tube. The cartridge incorporates Sun's floating style construction to reduce potential binding from excessive torque or machining variations. It fits into a T-31A cavity and offers a capacity of up to 10 gpm (40 L/min). With a typical response time of 50 ms and maximum leakage at specified conditions of 10 in\u00b3/min (160 cc/min), this valve supports high switching frequencies up to 15,000 cycles per hour. The product's installation requires specific torque settings and includes Viton seal kits for both cartridge and coil components.

This solenoid-operated 4-way, 2-position cartridge is a direct-acting, balanced spool directional valve.
- The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.
- This valve is direct actuated and requires no minimum hydraulic pressure for operation.
- This cartridge has several manual override choices, including no manual override. See the CONFIGURATION section. Please note: Manual override functionality is not compatible with weatherized coils.
- On models equipped with the D or L control, the detent mechanism in the manual override is meant for temporary actuation. The D, L and T manual control assembly has a mechanical life expectancy of approximately 7,000 cycles.
- Cartridges with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- This valve utilizes a wet armature design. This means that the working fluid surrounds the armature and is exposed to the heat generated by the coil. This can be a factor if the coil is energized for long periods of time. Some fluids, notably water/glycol mixtures, break down at these temperatures over time and form varnishes that will affect the function of the cartridge.
- A wide variety of coil termination and voltage options are available, with and without surge protection. See the CONFIGURATION section.
- The solenoid's unique magnetic design results in a high efficiency solenoid, yielding high spool actuating force per Watt expended, leading to reliable valve shifting.
- Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction.
- Coil connector options offer ratings up to IP69K. See individual coil product pages for details. Additional weatherized coils and kits are available for more complete environmental protection.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
