The Sun Hydraulics DMDATBN72419 (DMDATBN72419) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve features a solenoid tube assembly that is fatigue rated for 5000 psi (350 bar) service, ensuring reliable operation under high-pressure conditions. The valve offers closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, especially suitable for pilot control applications where capacity is less critical. This model does not require a minimum hydraulic pressure to operate, making it versatile for various hydraulic systems. It includes manual override options with a detent mechanism designed for temporary actuation and has an expected mechanical life of approximately 7,000 cycles. The DMDATBN72419 is equipped with EPDM seals intended specifically for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. Additionally, the valve incorporates a wet armature design where the working fluid surrounds the armature which can be significant if the coil remains energized over extended periods. This could lead to breakdown of certain fluids like water-glycol mixtures at high temperatures. It supports interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The design also features Sun\u2019s floating style construction which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. Key specifications include a maximum flow capacity of 12 gpm (45 L/min), rapid response time typically around 50 ms, and a maximum operating pressure of 5000 psi (350 bar). The valve\u2019s robust construction and versatile design make it an efficient solution for demanding directional control applications in hydraulic systems.

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.
