The Sun Hydraulics DMDAMAV928 (DMDAMAV928) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust and efficient control in hydraulic systems. It features a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar), making it suitable for high-pressure applications. The valve operates with no minimum hydraulic pressure required, ensuring reliable performance across a range of conditions. The model incorporates closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times ideal for pilot control applications where capacity is less critical. Additionally, the DMDAMAV928 can be equipped with either D or L control options; these include a detent mechanism in the manual override designed primarily for temporary actuation. The mechanical life expectancy of this manual control assembly is approximately 7,000 cycles. For systems utilizing phosphate ester fluids, cartridges with EPDM seals are recommended to prevent damage from petroleum-based substances. The valve's wet armature design allows the working fluid to surround the armature which may require consideration regarding fluid type and operational duration due to potential heat exposure effects. This model also benefits from interchangeable coils compatible with other Sun Series 1 solenoid products and features Sun\u2019s floating style construction which minimizes internal parts binding caused by installation torque or machining variations. Key specifications include a maximum flow capacity of 12 gpm (45 L/min), rapid typical response time of 50 ms, and maximum switching frequency of 15,000 cycles/hr. The robust design coupled with versatile configurations makes the DMDAMAV928 an excellent choice for demanding hydraulic applications requiring precise directional control and reliable operation.

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.
