The Sun Hydraulics DMDAXNN624 (DMDAXNN624) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve is fatigue rated for up to 5000 psi (350 bar), making it suitable for heavy-duty applications. The valve features spools B and R which are closed during the transition between positions, enhancing performance by providing faster and more consistent response times, particularly beneficial in pilot control applications where capacity is less critical. The DMDAXNN624 operates without requiring a minimum hydraulic pressure, ensuring reliable functionality across a range of conditions. It includes manual override options with the D or L control, specifically designed for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. The valve is equipped with EPDM seals intended for use with phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. This model employs a wet armature design where the working fluid surrounds the armature, potentially affecting performance if the coil remains energized over extended periods due to heat exposure. It\u2019s compatible with interchangeable coils from other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The floating style construction of the valve minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. Additionally, technical specifications include a maximum flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and maximum leakage at 110 SUS (24 cSt) being limited to 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). The manual override requires a force of about 5 lbs at 1000 psi for port activation and has a stroke length of .10 inches (2.5 mm). This model's robust design coupled with its precise control capabilities makes it an optimal choice for advanced hydraulic circuit implementations requiring high reliability and efficiency.

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.
