The Sun Hydraulics DMDAMNV528 (DMDAMNV528) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed with a fatigue rating for 5000 psi (350 bar) service, making it suitable for rigorous applications. The solenoid tube assembly of the valve ensures durability and reliability under high-pressure conditions. The valve features closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times when used as pilot controls. This model is directly actuated and operates without requiring a minimum hydraulic pressure, which allows for flexibility in various hydraulic systems. It includes manual override options with a detent mechanism designed for temporary actuation; these models are expected to withstand approximately 7,000 cycles mechanically. Additionally, the DMDAMNV528 is equipped with EPDM seals suitable for systems using phosphate ester fluids; however, these seals must avoid exposure to petroleum-based fluids to prevent damage. Key specifications include a maximum flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and a maximum operating pressure of 5000 psi (350 bar). The valve's design incorporates Sun's floating style construction to minimize internal part binding due to installation torque or machining variations. Coils used in this model are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Overall, the Sun Hydraulics DMDAMNV528 offers robust construction and versatile performance characteristics suitable for demanding applications requiring precise control and reliability 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.
