The Sun Hydraulics DNDAXEV924N (DNDAXEV924N) is a solenoid-operated 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool directional design. Engineered with a solenoid tube assembly rated for fatigue at 5000 psi (350 bar), this valve operates without the need for minimum hydraulic pressure. It offers various manual override options, although compatibility with weatherized coils is limited. The manual control assemblies, specifically the D or L control models, include a detent mechanism intended for temporary actuation and have an estimated mechanical life of 7,000 cycles. Notably, cartridges equipped with EPDM seals are suitable for systems utilizing phosphate ester fluids but may suffer damage from petroleum-based substances. The valve employs a wet armature design where the working fluid surrounds the armature, potentially affecting function if exposed to prolonged coil heat\u2014especially in water-glycol mixtures which can degrade over time. This model offers flexibility in coil termination and voltage configurations, some with surge protection. Its unique magnetic design results in high efficiency and reliable shifting by maximizing spool actuating force per watt expended. Coils are interchangeable within the Sun Series 1 solenoid range and can be mounted bidirectionally on the tube. Additionally, it provides coil connector options rated up to IP69K for enhanced environmental protection. The Sun floating style construction minimizes internal part binding risks due to excessive torque or machining variations. With a capacity of 10 gpm (40 L/min) and a maximum operating pressure of 5000 psi (350 bar), this valve exhibits typical response times of 50 ms and leakage rates at maximum of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). It supports switching frequencies up to 15,000 cycles per hour and requires specific manual override forces during operation. Seal kits are available in Viton material 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.
