The Sun Hydraulics DNDATLN (Material Number: DNDATLN) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is engineered to handle up to 5000 psi (350 bar) service pressure and does not require a minimum hydraulic pressure for operation, making it highly versatile. The solenoid tube assembly is fatigue-rated for durability, and the valve features a wet armature design that allows the working fluid to surround the armature, which can be crucial when the coil is energized for prolonged periods. The DNDATLN model offers several manual override options, although manual override functionality is incompatible with weatherized coils. For models equipped with the D or L control, the detent mechanism in the manual override is intended for temporary actuation with an approximate mechanical life expectancy of 7,000 cycles. This cartridge supports systems using phosphate ester fluids through its EPDM seals but should avoid petroleum-based fluids to prevent damage. With a capacity of 10 gpm (40 L/min), this valve incorporates Sun's floating style construction to minimize internal part binding due to excessive installation torque or cavity machining variations. It features interchangeable coils with other Sun Series 1 solenoid products and offers coil connector options rated up to IP69K for enhanced environmental protection. The high-efficiency solenoid design yields significant spool actuating force per watt expended, ensuring reliable valve shifting. The response time is typically 50 ms, and it supports a switching frequency of up to 15,000 cycles per hour. Additional specifications include a cavity size of T-31A, a solenoid tube diameter of .75 inches (19 mm), and an installation torque requirement between 30-35 lbf ft (41-47 Nm). The valve also comes with Viton seal kits available for both cartridge and coil components.

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.
