The Sun Hydraulics DNDAXUN836 (DNDAXUN836) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. It features a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar) service pressure. This valve operates without needing minimum hydraulic pressure and offers multiple manual override options, though manual overrides are not compatible with weatherized coils. The manual control's detent mechanism is intended for temporary actuation with an approximate mechanical life expectancy of 7,000 cycles. The valve uses EPDM seals suitable for phosphate ester fluids while being vulnerable to petroleum-based substances. Its wet armature design allows working fluid to surround the armature, which can affect function if exposed to prolonged coil heat. The DNDAXUN836 offers high efficiency due to its unique magnetic solenoid design, ensuring reliable valve shifting with high actuating force per watt expended. Compatible with other Sun Series 1 solenoid products, the coils can be mounted in either direction and offer various termination and voltage options with surge protection availability. Coil connectors are rated up to IP69K for enhanced environmental protection, and additional weatherized coils and kits are available. The valve incorporates Sun's floating style construction, reducing internal binding risks due to excessive torque or machining variations. This cartridge fits a T-31A cavity and belongs to Series 1, offering 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 leakage rate at maximum pressure of 10 in\u00b3/min (160 cc/min) at 3000 psi (210 bar). With a switching frequency of up to 15,000 cycles/hour, its manual override requires a force of approximately 5 lbs/1000 psi on Port 1 with a stroke length of .10 inches (2.5 mm). The solenoid tube diameter measures .75 inches (19 mm), with an installation torque range between 30-35 lbf ft (41-47 Nm), weighing in at .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.
