The Sun Hydraulics DNDAMXE812 (DNDAMXE812) is a solenoid-operated 4-way, 2-position cartridge directional valve designed for high efficiency and reliability in hydraulic systems. This direct-acting, balanced spool valve requires no minimum hydraulic pressure for operation and is fatigue rated for service up to 5000 psi (350 bar). The valve features a wet armature design, where the working fluid surrounds the armature, exposing it to coil-generated heat. This design consideration is crucial when using fluids like water-glycol mixtures that may degrade at high temperatures. The DNDAMXE812 offers various manual override options and is configured with a detent mechanism intended for temporary actuation, with an approximate mechanical life expectancy of 7,000 cycles. It accommodates EPDM seals suitable for phosphate ester fluids but incompatible with petroleum-based substances. The solenoid's unique magnetic design provides high actuating force per watt, ensuring reliable valve shifting. A range of coil termination and voltage options are available, including those with surge protection. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted bi-directionally on the tube. For environmental resilience, coil connector options boast ratings up to IP69K, with additional weatherized coils available. The DNDAMXE812 supports a maximum flow capacity of 10 gpm (40 L/min) and features a typical response time of 50 milliseconds. It has a switching frequency capability of up to 15,000 cycles per hour and exhibits minimal leakage under specified conditions. This cartridge uses Sun's floating style construction to minimize internal binding risks due to installation torque or machining variations. The valve's compact design includes vital dimensions such as a .75-inch solenoid tube diameter and .78-inch hex size, making it suitable for diverse hydraulic applications requiring precise directional control.

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.
