The Sun Hydraulics DNDAMUE298 (DNDAMUE298) is a solenoid-operated, 4-way, 2-position cartridge valve that is direct-acting and features a balanced spool directional design. Engineered for high performance, the valve's solenoid tube assembly is fatigue rated for service up to 5000 psi (350 bar), ensuring durability and reliability in demanding applications. This valve operates without requiring minimum hydraulic pressure, making it versatile for various systems. It offers several manual override options, although manual override functionality is incompatible with weatherized coils. The D, L, and T control models include a detent mechanism for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. Designed with a wet armature configuration, the working fluid surrounds the armature and absorbs heat generated by the coil. This design consideration is crucial when using fluids like water-glycol mixtures that may degrade over time under prolonged exposure to elevated temperatures. The valve accommodates EPDM seals specifically suited for systems utilizing phosphate ester fluids; however, these seals are not compatible with petroleum-based substances. A range of coil termination and voltage options are available, including those with surge protection capabilities. Coils are interchangeable across Sun Series 1 solenoid products and can be mounted in either direction on the tube. With connector options rated up to IP69K, this valve ensures robust environmental protection when combined with additional weatherized coils and kits. The DNDAMUE298 incorporates Sun's floating style construction to minimize potential internal binding due to excessive installation torque or cavity/cartridge machining variations. It has a capacity of 10 gpm (40 L/min) and can operate at maximum pressures of 5000 psi (350 bar). The typical response time is approximately 50 ms, supporting high-frequency switching up to 15,000 cycles per hour.

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.
