The Sun Hydraulics DMDAXNN824 (DMDAXNN824) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust operation in demanding applications, featuring a fatigue rating for 5000 psi (350 bar) service. The solenoid tube assembly of the DMDAXNN824 ensures reliability and durability under continuous use. The valve's design includes closed transitions between Spools B and R, enhancing performance by ensuring faster and more consistent response times, ideal for pilot control applications where capacity is less critical. With no minimum hydraulic pressure required for operation, the DMDAXNN824 offers versatility across various hydraulic systems. This model incorporates EPDM seals suitable for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they could be damaged. The wet armature design of the valve allows the working fluid to surround the armature, which can affect fluid integrity if the coil remains energized over extended periods. Interchangeability of coils with other Sun Series 1 solenoid products adds to the flexibility of this model, allowing for easy maintenance and replacement. Additionally, the floating style construction minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. Key specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and a swift response time typically around 50 ms. Manual override options are available with a mechanical life expectancy of about 7,000 cycles. The compact size and moderate weight (.60 lb or 0.30 kg) make it suitable for various installation environments without compromising performance.

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.
