The Sun Hydraulics DMDADPV628 (DMDADPV628) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic fluid direction control. This direct-acting, balanced spool directional valve features a robust construction that is fatigue rated for 5000 psi (350 bar) service, ensuring reliable operation under high-pressure conditions. The valve's spool transitions are closed between positions B and R, enhancing performance by providing faster and more consistent response times, especially suitable for applications as pilot controls where flow capacity is less critical. The DMDADPV628 operates without requiring a minimum hydraulic pressure, making it versatile for various installation environments. It includes manual override options with detent mechanisms designed for temporary actuation; these are particularly useful in emergency or manual operation scenarios. The mechanical life expectancy of the manual control assembly is about 7,000 cycles, indicating its durability. For compatibility with different hydraulic fluids, the cartridges configured with EPDM seals are specifically designed for phosphate ester-based systems. However, exposure to petroleum-based fluids can damage these seals. The valve also features a wet armature design; thus, it is crucial to consider the type of fluid used as some may degrade at higher temperatures influenced by prolonged coil energization. This model incorporates interchangeable coils compatible with other Sun Series 1 solenoid products and utilizes Sun's floating style construction which minimizes internal parts binding due to installation variances. With a maximum operating pressure of 5000 psi and a capacity of 12 gpm (45 L/min), the DMDADPV628 is an efficient solution for managing directional control in hydraulic systems across various 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.
