The Sun Hydraulics DMDADNV528 (DMDADNV528) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve is engineered for robust operation with a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min). The valve features a fatigue-rated solenoid tube assembly suitable for demanding applications, ensuring reliable performance even under extreme conditions. Key to the DMDADNV528\u2019s functionality is its closed transition between spools B and R, which enhances performance by ensuring faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. The valve operates without the need for minimum hydraulic pressure, making it versatile across various hydraulic systems. Additionally, the model incorporates manual override options with a detent mechanism designed for temporary actuation. Its mechanical life expectancy stands at approximately 7,000 cycles. For environments utilizing phosphate ester fluids, cartridges equipped with EPDM seals are recommended to prevent damage from petroleum-based substances. This valve also benefits from Sun Hydraulics' innovative wet armature design and floating style construction which minimizes internal binding due to installation torque or machining variations. It supports a switching frequency of up to 15,000 cycles per hour and features interchangeable coils compatible with other Sun Series 1 solenoid products. The manual override requires minimal force, and its quick response time is typically around 50 ms, making it an excellent choice for systems requiring rapid directional changes in fluid flow.

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.
