The Sun Hydraulics DMDATNN624N (DMDATNN624N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is specifically designed for robust industrial applications requiring precise control over fluid direction. The valve features a fatigue rating of 5000 psi (350 bar), making it suitable for high-pressure systems. Its spools, B and R, maintain a closed state during transitions between positions to enhance performance by offering faster and more consistent response times ideal for pilot control applications where capacity is less critical. The DMDATNN624N operates without requiring a minimum hydraulic pressure, providing flexibility in various operating conditions. It incorporates manual override options with a detent mechanism designed for temporary actuation; these models are expected to withstand approximately 7,000 cycles. Additionally, the valve is equipped with EPDM seals intended for use with phosphate ester fluids; however, these seals must avoid exposure to petroleum-based substances to prevent damage. This model utilizes a wet armature design where the working fluid surrounds the armature\u2014important in scenarios where the coil may be energized continuously, potentially affecting fluid integrity over time. The interchangeable coils compatible with other Sun Series 1 solenoid products offer installation versatility and are designed to minimize internal part binding due to installation torque or machining variations of cavity/cartridge. Key specifications include a flow capacity of 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and maximum valve leakage at specified conditions. The robust construction and thoughtful design details make the DMDATNN624N an effective 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.
