The Sun Hydraulics DMDAXPN628 (DMDAXPN628) 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 fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar), making it suitable for robust applications. The valve ensures closed transitions between Spools B and R, optimizing performance by prioritizing faster and more consistent response times over capacity, which is especially beneficial in pilot control applications where capacity is less critical. This model incorporates a wet armature design wherein the working fluid surrounds the armature, potentially affecting fluid properties if exposed to prolonged heat from an energized coil. It is important to note that cartridges with EPDM seals are specifically designed for use with phosphate ester fluids and should not be exposed to petroleum-based substances. The DMDAXPN628 offers interchangeable coils with other Sun Series 1 solenoid products and features a floating style construction that minimizes internal parts binding due to installation or machining discrepancies. With a maximum flow capacity of 12 gpm (45 L/min) and quick response times typically around 50 ms, this valve is engineered for efficiency and reliability in various hydraulic systems. Additional specifications include a manual override mechanism intended for temporary actuation with an estimated mechanical life of about 7,000 cycles. This model's robust construction and versatile design make it an essential component for controlled hydraulic operations across multiple 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.
