The Sun Hydraulics DNDAXCN736 (DNDAXCN736) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This model is engineered with a fatigue-rated solenoid tube assembly, suitable for service pressures up to 5000 psi (350 bar), ensuring robust performance in demanding hydraulic applications. The valve operates without the need for minimum hydraulic pressure, making it versatile for various system requirements. It features multiple manual override options and incorporates a wet armature design, which allows the working fluid to cool the coil but requires careful selection of compatible fluids to prevent varnish formation over prolonged coil energization. The DNDAXCN736 offers a high-efficiency solenoid with significant spool actuating force per watt consumed, ensuring reliable shifting and efficiency in operation. Coils are interchangeable with other Sun Series 1 products and can be mounted bi-directionally on the tube. The valve's construction minimizes internal binding risks due to excessive torque or machining variations, enhancing durability and reliability. Capable of handling flow rates up to 10 gpm (40 L/min) and offering rapid response times typically around 50 ms, this cartridge valve is suitable for applications requiring frequent switching, with a switching frequency of up to 15,000 cycles per hour. The valve also supports various coil termination and voltage configurations, including options with surge protection and IP69K-rated connectors for enhanced environmental protection. With a compact design featuring a .75-inch solenoid tube diameter and a hex size of .78 inches, the DNDAXCN736 is easy to install with recommended torque settings between 30-35 lbf ft (41-47 Nm). This model weighs approximately .60 lb (.30 kg) and uses Viton seal kits for compatibility with different fluid types.

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.
