The Sun Hydraulics DNDATLN736 (DNDATLN736) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This robust valve features a solenoid tube assembly that is fatigue-rated for up to 5000 psi (350 bar) service, ensuring reliable performance in demanding applications. Notably, it requires no minimum hydraulic pressure for operation, making it versatile in various hydraulic systems. The valve offers several manual override options, including configurations without a manual override; however, it's important to note that the manual override is not compatible with weatherized coils. The D and L control models include a detent mechanism intended for temporary actuation with an approximate mechanical life expectancy of 7,000 cycles. This cartridge employs a wet armature design where the working fluid surrounds the armature. While this design enhances efficiency by providing high spool actuating force per Watt expended, it also necessitates consideration of fluid compatibility as prolonged coil energization can degrade certain fluids like water-glycol mixtures. The DNDATLN736 supports various coil termination and voltage options and features interchangeable coils with other Sun Series 1 solenoid products. The valve's construction incorporates Sun's floating style design to minimize internal binding due to installation torque or machining variations. It fits into cavity T-31A and has a capacity of 10 gpm (40 L/min), with a typical response time of 50 ms and maximum leakage at specified conditions of 10 in\u00b3/min (3000 psi). This model comes with Viton seal kits available for both the cartridge and coil components. With its high switching frequency capability of up to 15,000 cycles per hour and IP69K-rated coil connector options, the DNDATLN736 is well-suited for applications requiring reliable directional flow control under varying environmental conditions.

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.
