The Sun Hydraulics DMDAMRNHN24AB (DMDAMRNHN24AB) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for direct-acting operation with a balanced spool. This valve does not require a minimum hydraulic pressure to function, making it versatile for various applications. It features fatigue-rated solenoid tube assemblies capable of handling up to 5000 psi (350 bar), suitable for demanding environments. The model includes spools B and R, which are closed during the transition between positions to enhance performance limits at the cost of lower capacity. However, this design choice benefits applications where speed and consistency in response times are critical, such as pilot controls. The DMDAMRNHN24AB is equipped with manual override options (D or L control) that include a detent mechanism intended for temporary actuation, with a mechanical life expectancy of around 7,000 cycles. For compatibility with different fluid types, cartridges configured with EPDM seals are specifically used in systems containing phosphate ester fluids; however, they must avoid exposure to petroleum-based fluids which could damage the seals. The valve's wet armature design allows the working fluid to surround the armature and absorb heat from the coil\u2014important to consider if the coil remains energized over extended periods. Additionally, this model's coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. It also incorporates Sun\u2019s floating style construction which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. With a flow capacity of up to 12 gpm (45 L/min) and quick response times typically around 50 ms, this valve supports efficient operation across various hydraulic applications.

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.
