The Sun Hydraulics DNDAMTV814 (DNDAMTV814) is a solenoid-operated 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. Engineered for high-performance applications, this valve operates efficiently with no minimum hydraulic pressure requirement and is fatigue-rated for service up to 5000 psi (350 bar). Its wet armature design ensures that the working fluid surrounds the armature, although prolonged coil energization can affect fluid stability in certain mixtures like water-glycol. The DNDAMTV814 offers multiple manual override configurations, though models with weatherized coils are incompatible with this feature. The manual control assembly in specific models has a mechanical life expectancy of approximately 7,000 cycles. Designed with high efficiency in mind, the solenoid provides substantial spool actuating force per Watt expended, ensuring reliable valve shifting. Interchangeable coils with other Sun Series 1 solenoid products enhance versatility and can be mounted bi-directionally on the tube. Coil connector options are available up to IP69K ratings for robust environmental protection. Incorporating Sun's floating style construction helps minimize potential internal part binding due to excessive installation torque or machining variations. With a capacity of 10 gpm (40 L/min) and a rapid typical response time of 50 ms, this valve is suitable for demanding applications requiring frequent switching up to 15,000 cycles per hour. The cartridge features Viton seal kits for compatibility with various fluids but requires EPDM seals when used with phosphate ester fluids to prevent damage from petroleum-based substances. This model's compact dimensions include a solenoid tube diameter of .75 inches (19 mm) and an installation torque range of 30-35 lbf ft (41-47 Nm), making it adaptable to numerous hydraulic systems within its operational specifications.

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.
