The Sun Hydraulics DMDAXNN72419 (DMDAXNN72419) is a high-performance solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool directional design. Engineered for precision and reliability, this valve operates without the need for minimum hydraulic pressure. It is particularly suitable for applications requiring consistent and fast response times due to its closed transitions between positions B and R, enhancing performance at the cost of capacity which is not crucial in pilot control setups. The valve boasts a robust fatigue rating of 5000 psi (350 bar) for its solenoid tube assembly, making it an excellent choice for demanding environments. The manual override options (D, L, T controls) provide temporary actuation with a mechanical life expectancy of about 7,000 cycles. Additionally, the DMDAXNN72419 utilizes EPDM seals specifically designed for use with phosphate ester fluids; however, these seals are vulnerable to damage when exposed to petroleum-based substances. This model also incorporates a wet armature design where the working fluid surrounds the armature\u2014important to consider in scenarios where the coil may be energized continuously as it affects fluid integrity over time. The interchangeable coils enhance flexibility and ease of maintenance by being compatible with other Sun Series 1 solenoid products. Practical installation benefits include Sun's floating style construction which minimizes internal parts binding due to variations in installation torque or cavity/cartridge machining. With additional features like a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and rapid typical response times around 50 ms, the DMDAXNN72419 is engineered to meet rigorous industrial demands while providing exceptional operational efficiency 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.
