The Sun Hydraulics DMDAXPV528 (DMDAXPV528) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. Featuring a direct-acting, balanced spool directional valve mechanism, it ensures precise control and operation in various settings. This model is particularly noted for its fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), making it suitable for high-pressure environments. The DMDAXPV528 utilizes a closed transition between spools B and R, enhancing performance by ensuring faster and more consistent response times, ideal for applications where capacity is less critical but speed and reliability are paramount. It operates without requiring a minimum hydraulic pressure, adding to its versatility in different hydraulic systems. Equipped with EPDM seals, the DMDAXPV528 is compatible with phosphate ester fluids, although it should not be exposed to petroleum-based fluids which can damage the seals. The wet armature design of the valve allows the working fluid to surround the armature which may be a consideration in applications where the coil remains energized for extended periods. For maintenance or manual control, this model includes a detent mechanism in the manual override suitable for temporary actuation with an estimated mechanical life expectancy of around 7,000 cycles. Additionally, its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. This valve also features Sun's floating style construction which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. With a maximum operating capacity of 12 gpm (45 L/min) and quick response time typically around 50 ms, the DMDAXPV528 is an optimal choice for dynamic hydraulic systems requiring reliable directional 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.
