The Sun Hydraulics DNDAXYN71299 (DNDAXYN71299) is a solenoid-operated, 4-way, 2-position cartridge valve, designed for direct-acting and balanced spool directional control. This robust valve is rated for fatigue service up to 5000 psi (350 bar) and does not require minimum hydraulic pressure for operation. It offers several manual override options, though manual override functionality is incompatible with weatherized coils. The model includes a detent mechanism in the manual override for temporary actuation, with a mechanical life expectancy of approximately 7,000 cycles. Cartridges equipped with EPDM seals are suitable for systems using phosphate ester fluids but can be damaged by petroleum-based substances. The valve's wet armature design allows the working fluid to surround the armature, which may impact performance if the coil is energized for extended periods. The DNDAXYN71299 features a high-efficiency solenoid design that provides significant spool actuating force per watt expended, ensuring reliable valve shifting. Coils can be interchanged with other Sun Series 1 solenoid products and mounted in either direction. Various coil termination and voltage options are available, some offering surge protection and ratings up to IP69K for enhanced environmental protection. This model incorporates Sun's floating style construction to minimize internal part binding due to excessive installation torque or machining variations. Key specifications include a cavity T-31A, Series 1 classification, a capacity of 10 gpm (40 L/min), and maximum operating pressure of 5000 psi (350 bar). It has a typical response time of 50 ms and maximum valve leakage at 110 SUS (24 cSt) of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). The switching frequency reaches up to 15,000 cycles per hour. Installation requires a torque range between 30-35 lbf ft (41-47 Nm), with the valve weighing approximately .60 lb (.30 kg).

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.
