The Sun Hydraulics DMDADBN624N (DMDADBN624N) 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 seamlessly manages the flow and direction of hydraulic fluids within a system. Featuring a fatigue rating of 5000 psi (350 bar), this valve is engineered to withstand rigorous operational demands, making it suitable for heavy-duty applications. The DMDADBN624N utilizes a closed transition between Spools B and R, optimizing performance by ensuring faster and more consistent response times ideal for pilot control systems where capacity is less critical. Additionally, it operates without requiring a minimum hydraulic pressure, enhancing its versatility across various hydraulic setups. This model incorporates a wet armature design where the working fluid surrounds the armature. Such configuration is crucial for understanding the thermal dynamics as it can affect fluid integrity under prolonged coil energization. It is equipped with EPDM seals specifically designed for compatibility with phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. For maintenance or manual control, the valve features a detent mechanism in the manual override which is intended for temporary actuation with an estimated mechanical life of about 7,000 cycles. The interchangeable coils compatible with other Sun Series 1 solenoid products offer flexibility in repairs or upgrades. Moreover, its construction includes Sun's floating style which minimizes internal part binding due to installation stresses or machining variations. With specifications like a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and rapid response times typically around 50 ms, the Sun Hydraulics DMDADBN624N valve stands out as an efficient solution for advanced hydraulic system controls where reliability and performance are paramount.

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.
