The Sun Hydraulics DMDATBN724N (DMDATBN724N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic system control. This direct-acting, balanced spool directional valve operates without the need for a minimum hydraulic pressure, enhancing its reliability and performance in various applications. The valve features a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar), ensuring durability and resilience under high-pressure conditions. It is specifically engineered with closed transitions between spools B and R to achieve faster and more consistent response times, particularly beneficial in pilot control setups where capacity is less critical. This model incorporates a wet armature design which allows the working fluid to surround the armature, mitigating the risk of overheating during prolonged coil energization. However, this design necessitates careful consideration of fluid types as certain fluids like water-glycol mixtures may degrade at higher temperatures. For systems using phosphate ester fluids, cartridges with EPDM seals are recommended to avoid damage from petroleum-based substances. The DMDATBN724N is versatile with interchangeable coils compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. It also employs Sun\u2019s floating style construction to minimize internal parts binding caused by excessive installation torque or machining variations of cavity/cartridge. Key specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity of up to 12 gpm (45 L/min), and typical response time of 50 ms. The manual override mechanism provided is intended for temporary actuation only, with a mechanical life expectancy around 7,000 cycles. This valve is an excellent choice for applications requiring robust performance, rapid response times, and flexibility in fluid compatibility and installation configurations.

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.
