The Sun Hydraulics DMDAMRNHN24AA (DMDAMRNHN24AA) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve integrates seamlessly into a variety of applications, particularly where rapid and consistent response times are crucial. Engineered for durability, the solenoid tube assembly is rated for fatigue at 5000 psi (350 bar), making it suitable for demanding environments. The valve features closed transitions between Spools B and R, enhancing performance by ensuring faster switching times albeit at a reduced capacity. This characteristic is particularly beneficial in pilot control applications where capacity demands are lower. The DMDAMRNHN24AA operates without requiring a minimum hydraulic pressure, thereby providing versatility across various hydraulic circuits. For manual override operations, the valve includes detent mechanisms designed to support temporary actuation with an estimated mechanical life of around 7,000 cycles. It also offers flexibility in terms of seal configurations; models with EPDM seals are compatible with phosphate ester fluids but should avoid contact with petroleum-based substances which can degrade the seals. This model employs a wet armature design where the working fluid cools the armature, although prolonged energization could lead to fluid degradation in certain conditions. Furthermore, its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction to accommodate different installation requirements. The construction utilizes Sun's floating style to minimize internal binding caused by installation or machining variations. With specifications including a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and typical response time of 50 ms, the DMDAMRNHN24AA is engineered to meet rigorous industrial standards while ensuring reliable and 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.
