The Sun Hydraulics DNDAXHN928 (DNDAXHN928) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This versatile valve operates effectively at a fatigue-rated pressure of up to 5000 psi (350 bar), requiring no minimum hydraulic pressure for activation. It features several manual override options, though these are not compatible with weatherized coils. The manual override's detent mechanism in models with D or L control is intended for temporary actuation and has a mechanical life expectancy of around 7,000 cycles. For systems using phosphate ester fluids, cartridges with EPDM seals are recommended due to potential damage from petroleum-based substances. The wet armature design enhances efficiency but may affect certain fluid types over prolonged coil energization. With interchangeable coils and various termination and voltage options available, the valve supports customization for specific needs while offering IP69K-rated coil connectors for enhanced environmental protection. The Sun floating style construction minimizes the risk of internal binding from excessive torque or machining variations. Suitable for cavity T-31A and Series 1 applications, it offers a capacity of 10 gpm (40 L/min) and a typical response time of 50 ms. Maximum leakage is limited to 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar), while the valve supports switching frequencies up to 15,000 cycles per hour. Installation requires a torque of 30\u201335 lbf ft (41\u201347 Nm), with a manual override force of approximately 5 lbs/1000 psi at Port 1 (33 N/100 bar). With its robust design and high efficiency, this cartridge valve is suitable for demanding hydraulic applications requiring reliable performance and durability.

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.
