The Sun Hydraulics DMDALBN828 (DMDALBN828) is a solenoid-operated 3-way, 2-position cartridge valve, engineered for high performance in hydraulic systems. It features a direct-acting, balanced spool directional control mechanism that ensures reliable operation without the need for minimum hydraulic pressure. This model is particularly noted for its fatigue-rated solenoid tube assembly which can handle services up to 5000 psi (350 bar), making it suitable for demanding applications. The valve's design incorporates closed transitions between Spools B and R, optimizing performance by allowing faster and more consistent response times, especially useful in pilot control applications where capacity is less critical. The wet armature design of the valve facilitates the surrounding of the armature by working fluid, which helps in heat management but requires careful selection of fluid types to avoid breakdown and varnish formation that could impair functionality. This model is compatible with EPDM seals specifically designed for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. For maintenance and longevity, the manual override feature equipped with D or L control includes a detent mechanism designed for temporary actuation with a mechanical life expectancy of about 7,000 cycles. Additionally, the DMDALBN828 facilitates easy integration and interchangeability within Sun Series 1 solenoid products thanks to its standardized coil features. This includes interchangeable coils which can be mounted in either direction on the tube and incorporates Sun\u2019s floating style construction that minimizes internal parts binding. This model supports a flow capacity of up to 12 gpm (45 L/min) and offers quick response times typically around 50 ms, making it an efficient choice for various hydraulic system applications requiring robust control and reliability.

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.
