The Sun Hydraulics DNDAMXN812 (DNDAMXN812) is a solenoid-operated 4-way, 2-position cartridge valve designed as a direct-acting, balanced spool directional valve. This versatile component features a fatigue-rated solenoid tube assembly capable of withstanding up to 5000 psi (350 bar), ensuring robust performance in demanding applications. Notably, it requires no minimum hydraulic pressure for operation, making it suitable for various systems. The valve offers several manual override options; however, these are not compatible with weatherized coils. Models equipped with D or L control have a detent mechanism meant for temporary actuation, with a mechanical life expectancy of approximately 7,000 cycles. This cartridge valve incorporates EPDM seals specifically for use in systems utilizing phosphate ester fluids; exposure to petroleum-based fluids can damage the seals. The wet armature design allows working fluid to surround the armature and be exposed to heat generated by the coil\u2014a consideration when the coil is energized for extended periods as some fluids may degrade over time. Offering high efficiency due to its unique magnetic design, this solenoid provides reliable valve shifting with high spool actuating force per Watt expended. It supports interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction. Coil connector options offer ratings up to IP69K for enhanced environmental protection. The Sun floating style construction minimizes internal part binding due to excessive installation torque or cavity-cartridge machining variations. With a capacity of 10 gpm (40 L/min), this model is ideal for operations requiring precise control and reliability under high-pressure conditions. Additional specifications include a typical response time of 50 ms and maximum valve leakage at 110 SUS (24 cSt) of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar).

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.
