The Sun Hydraulics DNDAMXE (DNDAMXE) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This robust valve operates efficiently with no minimum hydraulic pressure requirement, making it versatile for various hydraulic systems. It features a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar) service pressure. The valve incorporates a wet armature design, ensuring that the working fluid surrounds the armature to dissipate heat effectively during prolonged coil energization. However, users should be cautious with certain fluids like water-glycol mixtures that may degrade at high temperatures. The DNDAMXE offers several manual override options, though users should note that manual overrides are incompatible with weatherized coils. The detent mechanism in models equipped with D or L control is intended for temporary actuation and has a mechanical life expectancy of approximately 7,000 cycles. This cartridge is particularly suitable for systems using phosphate ester fluids when equipped with EPDM seals; however, exposure to petroleum-based fluids can damage these seals. With a capacity of 10 gpm (40 L/min), this valve delivers reliable performance and boasts a typical response time of 50 ms. It supports a switching frequency of up to 15,000 cycles per hour and maintains maximum valve leakage at 10 in\u00b3/min (160 cc/min) at 3000 psi (210 bar). The cartridge's floating style construction minimizes internal binding risks due to installation torque variations or cavity machining discrepancies. A variety of coil termination and voltage options are available, including surge protection features. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. For enhanced environmental protection, additional weatherized coils and kits are also offered.

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.
