The Sun Hydraulics DMDALAN812 (DMDALAN812) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust and precise hydraulic control. This direct-acting, balanced spool directional valve is ideal for applications requiring reliable switching and control of hydraulic fluids. It operates efficiently with a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min). The DMDALAN812 features an innovative wet armature design, where the working fluid surrounds the armature, optimizing heat dissipation during prolonged operation. This design characteristic is crucial in preventing the breakdown of certain hydraulic fluids under high temperature. The valve\u2019s solenoid tube assembly is fatigue rated for demanding conditions, ensuring durability and long-term performance. Notably, this model includes a manual override with a detent mechanism designed for temporary actuation, enhancing operational flexibility. This feature is particularly useful in scenarios where manual intervention is required to override automated processes temporarily. The mechanical life expectancy of the manual control assembly in this valve reaches approximately 7,000 cycles. For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended to avoid damage from petroleum-based substances. Additionally, its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction to accommodate different installation requirements. The DMDALAN812 incorporates Sun's floating style construction which minimizes internal parts binding due to excessive installation torque or machining variations in the cavity/cartridge setup. This feature contributes significantly to the reliability and maintenance ease of the valve in various industrial 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.
