The Sun Hydraulics DMDAMNV848 (DMDAMNV848) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed to offer reliable control in hydraulic systems. The valve features a robust solenoid tube assembly that is fatigue rated for up to 5000 psi (350 bar), making it suitable for demanding applications. With a maximum flow capacity of 12 gpm (45 L/min) and rapid response times typically around 50 ms, it ensures efficient operation and quick actuation. The DMDAMNV848 valve incorporates closed transitions between spool positions B and R, enhancing performance by ensuring faster and more consistent response times, particularly beneficial in pilot control applications where capacity is less critical. The manual override feature includes a detent mechanism meant for temporary actuation with an estimated mechanical life of about 7,000 cycles. Additionally, this model can be used with phosphate ester fluids when configured with EPDM seals; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. This model also benefits from a wet armature design where the working fluid surrounds the armature; this design consideration is crucial when the coil remains energized for extended periods as it could lead to fluid breakdown in certain conditions. For versatility in installation and maintenance, the coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Sun Hydraulics has also integrated their floating style construction into this model which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This feature contributes to the overall durability and reliability of the valve in various hydraulic system configurations.

This solenoid-operated 3-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.
- Spools B and R are closed in the transition between their two positions. This results in a higher performance limit at the expense of lower capacity. When used as pilot controls, where capacity is not a factor, the closed transition will provide faster and more consistent response times.
- This valve is direct actuated and requires no minimum hydraulic pressure for operation.
- 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 configured 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.
- Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction.
- 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.
