The Sun Hydraulics DMDAMNNHN24AB (DMDAMNNHN24AB) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve is notable for its robust construction, with a solenoid tube assembly that is fatigue rated for service up to 5000 psi (350 bar), ensuring reliability under demanding conditions. The valve features closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times, especially suitable for applications as pilot controls where capacity is less critical. With no minimum hydraulic pressure required for operation, the DMDAMNNHN24AB offers versatility in various hydraulic setups. It includes options for manual override through D, L, or T control assemblies; however, these are primarily intended for temporary actuation with a mechanical life expectancy of around 7,000 cycles. Additionally, when configured with EPDM seals, this model is compatible with phosphate ester fluids but should avoid contact with petroleum-based substances which could degrade the seals. The design incorporates a wet armature setup where the working fluid surrounds the armature. This feature necessitates consideration of fluid type and operational duration as heat from prolonged coil energization can lead to fluid degradation. For maintenance and customization ease, its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. This model also benefits from Sun's floating style construction which minimizes internal parts binding due to installation torque or machining variations of the cavity/cartridge. With a maximum flow capacity of 12 gpm (45 L/min), response times typically around 50 ms, and very low leakage rates at high pressures, the DMDAMNNHN24AB stands out as a reliable choice for advanced hydraulic systems requiring precise control and durability.

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.
