The Sun Hydraulics DNDAMUV836 (DNDAMUV836) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is engineered to withstand a fatigue rating of up to 5000 psi (350 bar), offering robust performance without requiring minimum hydraulic pressure for operation. It features multiple manual override options, though compatibility with weatherized coils is limited. The valve incorporates a wet armature design that immerses the armature in working fluid, which can impact performance if the coil remains energized for extended periods. This design consideration is particularly relevant when using fluids like water-glycol mixtures that may degrade under heat exposure. The valve's solenoid exhibits high efficiency through its unique magnetic design, ensuring reliable actuation with minimal energy expenditure. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The DNDAMUV836 offers various coil termination and voltage options, some equipped with surge protection and rated up to IP69K for enhanced environmental resilience. With a capacity of 10 gpm (40 L/min) and a typical response time of 50 ms, this cartridge ensures efficient fluid control in demanding applications. It supports a maximum operating pressure of 5000 psi (350 bar) and maintains low leakage rates at specified viscosity levels. The valve's construction follows Sun's floating style approach to minimize risks of internal binding due to installation torque or machining variations. Weighing just 0.60 lb (0.30 kg), it fits into T31A cavities and requires an installation torque between 30-35 lbf-ft (41-47 Nm). For systems using phosphate ester fluids, EPDM seals are recommended to prevent damage from petroleum-based substances.

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.
