The Sun Hydraulics DNDAXTV (DNDAXTV) is a solenoid-operated 4-way, 2-position cartridge valve designed for precise directional control in hydraulic systems. This direct-acting, balanced spool valve is engineered for high-efficiency operation and does not require a minimum hydraulic pressure to function. It features a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar), making it suitable for demanding applications. The DNDAXTV model offers several manual override options, although manual override functionality is not compatible with weatherized coils. For models with the D or L control, the detent mechanism in the manual override is intended for temporary actuation, with an estimated mechanical life of approximately 7,000 cycles. The valve's design incorporates a wet armature system, where the working fluid surrounds the armature and absorbs heat from the coil. This design consideration is crucial when using fluids such as water-glycol mixtures that may degrade under prolonged exposure to heat. The DNDAXTV accommodates various coil termination and voltage configurations, including options with surge protection. It also features interchangeable coils compatible with Sun Series 1 solenoid products. Key specifications include a capacity of 10 gpm (40 L/min), typical response time of 50 ms, maximum leakage at 110 SUS (24 cSt) of 10 in\u00b3/min (160 cc/min) at 3000 psi (210 bar), and a switching frequency of up to 15,000 cycles per hour. The cartridge utilizes Sun's floating style construction to reduce internal binding risks due to installation torque or machining variations. Additionally, it supports IP69K-rated coil connectors for enhanced environmental protection and offers seal kits compatible with Viton materials for robust performance in various fluid systems.

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.
