The Sun Hydraulics DMDAXAV528 (DMDAXAV528) is a solenoid-operated 3-way, 2-position cartridge valve that offers precise control and robust performance for hydraulic systems. It features a direct-acting, balanced spool design which ensures reliable operation without the need for minimum hydraulic pressure. The valve operates with a maximum capacity of 12 gpm (45 L/min) and can withstand pressures up to 5000 psi (350 bar). Its response time is notably quick at approximately 50 ms. This model is particularly noted for its closed transition spools B and R, enhancing performance by ensuring no overlap occurs during position changes, which is ideal for applications requiring fast and consistent response times such as pilot controls. The DMDAXAV528 incorporates a wet armature design where the working fluid surrounds the armature, crucial for understanding thermal effects during prolonged coil energization. The valve's manual override option, equipped with a detent mechanism, is designed primarily for temporary actuation with an estimated mechanical life of around 7,000 cycles. For environments using phosphate ester fluids, cartridges fitted with EPDM seals are recommended to avoid damage from petroleum-based substances. Additionally, this model benefits from Sun's floating style construction which minimizes internal part binding due to installation variances or cavity/cartridge machining errors. The interchangeable coils compatible with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement processes. With its robust construction and versatile design features, the DMDAXAV528 is engineered to meet high-performance demands in various hydraulic applications.

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.
