The Sun Hydraulics DMDATNN72499 (DMDATNN72499) is a solenoid-operated, 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve is notable for its robust construction and high-performance capabilities. It features a solenoid tube assembly that is fatigue rated for 5000 psi (350 bar), ensuring durability and reliability under high-pressure conditions. The valve operates with closed transitions between positions B and R, enhancing performance by providing faster and more consistent response times, especially suitable for applications as pilot controls where capacity is less critical. The DMDATNN72499 requires no minimum hydraulic pressure to function and includes manual override options with a detent mechanism designed for temporary actuation. Its mechanical life expectancy stands at approximately 7,000 cycles when equipped with D, L, or T manual control assemblies. Furthermore, the valve uses EPDM seals suitable for systems utilizing phosphate ester fluids; however, these seals are susceptible to damage from petroleum-based fluids. Equipped with a wet armature design, the working fluid in this model surrounds the armature which can be a consideration if the coil remains energized over extended periods. The valve's design also incorporates interchangeable coils compatible with other Sun Series 1 solenoid products and features Sun's floating style construction to minimize internal parts binding due to installation torque or cavity/cartridge machining variations. Key specifications include a flow capacity of up to 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and maximum leakage at 3000 psi set at 5 in\u00b3/min. The switching frequency can reach up to 15,000 cycles/hr. These attributes make the DMDATNN72499 an efficient choice for various hydraulic applications requiring precise control and reliability.

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.
