The Sun Hydraulics DMDAMNN628 (DMDAMNN628) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve features a fatigue rating for 5000 psi (350 bar) service, ensuring reliability under high-pressure conditions. The valve's design includes closed transitions between spools B and R, optimizing performance by providing faster and more consistent response times especially in applications where capacity is not a critical factor. Equipped with either D or L control options, the DMDAMNN628 includes a manual override with a detent mechanism intended for temporary actuation. The mechanical life expectancy of the manual control assembly is about 7,000 cycles, making it suitable for applications requiring frequent adjustments. Notably, cartridges with EPDM seals are specifically designed for use with phosphate ester fluids; however, they are not compatible with petroleum-based fluids which can damage the seals. This model also utilizes a wet armature design allowing the working fluid to surround the armature which helps in heat management during prolonged energization of the coil. It\u2019s important to note that certain fluids like water-glycol mixtures may degrade under sustained high temperatures. The interchangeable coils with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement processes. Additional features include Sun\u2019s floating style construction that minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. The valve supports up to 12 gpm (45 L/min) capacity and has an impressive response time typically around 50 ms. With maximum operating pressures up to 5000 psi (350 bar), and switching frequency capabilities up to 15,000 cycles/hr, this valve is engineered for robust performance in demanding 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.
