The Sun Hydraulics DNDATLN812 (DNDATLN812) is a solenoid-operated, 4-way, 2-position cartridge that functions as a direct-acting, balanced spool directional valve. This versatile valve is designed for high-performance applications, featuring a solenoid tube assembly rated for 5000 psi (350 bar) service. It operates without the need for minimum hydraulic pressure and offers several manual override options, including models without manual override capability. The D and L control models incorporate a detent mechanism in the manual override for temporary actuation with an approximate mechanical life expectancy of 7,000 cycles. Notably, EPDM seal variants are intended for systems utilizing phosphate ester fluids only, as exposure to petroleum-based substances can cause damage. The valve's wet armature design ensures that the working fluid surrounds the armature and absorbs heat generated by the coil. This feature is crucial when considering long-term coil energization since certain fluids may break down over time due to heat exposure. The solenoid's unique magnetic design enhances efficiency by providing high spool actuating force per watt expended, leading to reliable valve shifting. Additionally, it offers various coil termination and voltage options with interchangeable coils compatible with other Sun Series 1 solenoid products. The DNDATLN812 incorporates Sun's floating style construction to minimize internal part binding due to excessive installation torque or cavity/cartridge machining variations. It fits into T31A cavities and has a capacity of 10 gpm (40 L/min) with a maximum operating pressure of 5000 psi (350 bar). Its response time is typically 50 ms with a maximum leakage rate of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). The valve supports switching frequencies up to 15,000 cycles per hour and requires specific manual override force and stroke parameters for operation.

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.
