The Sun Hydraulics DNDAMXV812N (DNDAMXV812N) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This high-performance valve is fatigue-rated for up to 5000 psi (350 bar) service and requires no minimum hydraulic pressure for operation. It features a wet armature design where the working fluid surrounds the armature, which can be crucial when the coil is energized for extended periods as some fluids may degrade at high temperatures. The valve provides several manual override options, although manual override functionality is not compatible with weatherized coils. The mechanical life expectancy of models equipped with D or L control detents is approximately 7,000 cycles. The DNDAMXV812N offers a maximum capacity of 10 gpm (40 L/min) and operates within a pressure range of up to 5000 psi (350 bar). Its typical response time is around 50 milliseconds, and it can handle a switching frequency of up to 15,000 cycles per hour. The valve incorporates Sun's floating style construction to minimize internal binding due to excessive installation torque or machining variations in the cavity/cartridge. This model supports various coil termination and voltage options with or without surge protection and allows interchangeable coils with other Sun Series 1 solenoid products. Coil connector options are available with ratings up to IP69K for enhanced environmental protection. The solenoid's magnetic design ensures high efficiency by delivering significant spool actuating force per watt expended, resulting in reliable valve shifting performance. With a manual override stroke of .10 inches (2.5 mm) and requiring an override force of 5 lbs/1000 psi at Port 1, this versatile valve suits diverse hydraulic applications demanding precise directional control without compromising on durability or efficiency.

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.
