The Sun Hydraulics DMDAMNN72499 (DMDAMNN72499) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic fluid direction control. This direct-acting, balanced spool directional valve stands out with its ability to operate without minimum hydraulic pressure, making it exceptionally versatile for various applications. The valve features a robust design with a fatigue rating of 5000 psi (350 bar), ensuring reliable operation under high-pressure conditions. This model is equipped with EPDM seals suitable for systems using phosphate ester fluids, although these seals must avoid exposure to petroleum-based fluids to prevent damage. The DMDAMNN72499 benefits from a wet armature design where the working fluid surrounds the armature, which is crucial in scenarios where the coil remains energized for extended periods. This can influence fluid integrity over time, particularly with water-glycol mixtures that may degrade and form varnishes affecting cartridge functionality. Furthermore, the valve incorporates interchangeable coils compatible with other Sun Series 1 solenoid products, adding to its flexibility in system design. It also employs Sun's floating style construction to minimize internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. With a maximum flow capacity of 12 gpm (45 L/min) and quick response times typically around 50 ms, the DMDAMNN72499 is capable of handling substantial flow rates efficiently while maintaining precise control. The manual override feature found in models with D or L control is designed for temporary actuation and supports mechanical life expectancy around 7,000 cycles. This model\u2019s practicality extends to easy installation and maintenance facilitated by its standard T11A cavity and common tooling requirements.

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.
