The Sun Hydraulics DMDAXBV824 (DMDAXBV824) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust and efficient hydraulic control. This direct-acting, balanced spool directional valve features a solenoid tube assembly that is fatigue rated for 5000 psi (350 bar) service, ensuring reliable operation under high-pressure conditions. The valve's design includes closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times, especially suitable for pilot controls where capacity is less critical. The DMDAXBV824 operates without requiring a minimum hydraulic pressure, enhancing its versatility across various applications. It incorporates a wet armature design where the working fluid surrounds the armature; this setup necessitates consideration of fluid type as heat generated by the coil during prolonged energization could degrade certain fluids like water-glycol mixtures. Additionally, the valve is compatible with EPDM seals specifically for use with phosphate ester fluids, avoiding damage that could be caused by exposure to petroleum-based substances. Interchangeable coils with other Sun Series 1 solenoid products add to the flexibility of this model, allowing for easy maintenance and configuration adjustments. The construction utilizes Sun's floating style to minimize internal parts binding due to installation torque or cavity/cartridge machining variations. This model's manual override feature is designed for temporary actuation with an expected mechanical life of approximately 7,000 cycles. Technical specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and typical response time of 50 ms. The valve also supports a switching frequency of up to 15,000 cycles per hour and features manual override options that require minimal force. These characteristics make the DMDAXBV824 ideal for sophisticated hydraulic systems demanding high-speed operation and precise control.

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.
