The Sun Hydraulics DMDAXBV828 (DMDAXBV828) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control in various applications. This direct-acting, balanced spool directional valve features a robust design with a solenoid tube assembly that is fatigue rated for 5000 psi (350 bar) service, ensuring reliable operation under high-pressure conditions. The valve's spools B and R maintain a closed transition between two positions, optimizing performance by providing faster and more consistent response times, especially suitable for pilot control applications where capacity is less critical. The DMDAXBV828 operates without requiring a minimum hydraulic pressure, enhancing its versatility across different hydraulic systems. It includes options for manual override controls (D, L, T types), each designed with a detent mechanism intended for temporary actuation with an estimated mechanical life of approximately 7,000 cycles. This model also supports EPDM seals specifically for use with phosphate ester fluids; however, it should not be exposed to petroleum-based fluids as they can damage the seals. A notable feature of the DMDAXBV828 is its wet armature design where the working fluid surrounds the armature exposed to heat from the coil. This design consideration is crucial when using fluids like water-glycol mixtures that may degrade at higher temperatures. The valve's coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction to accommodate varying installation requirements. Additionally, Sun Hydraulics has incorporated their floating style construction into this model to minimize internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With a maximum operating pressure of 5000 psi and a flow capacity of up to 12 gpm (45 L/min), the DMDAXBV828 provides a robust solution for efficient directional control 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.
