The Sun Hydraulics DMDAMRN528 (DMDAMRN528) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve is capable of operating with no minimum hydraulic pressure required, ensuring reliable functionality across a broad range of applications. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min), it is well-suited for demanding environments. The DMDAMRN528 features closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, particularly beneficial in pilot control applications where capacity is less critical. The valve incorporates a wet armature design, where the working fluid surrounds the armature which can be crucial when considering fluid compatibility and coil temperature impacts. Interchangeability of coils with other Sun Series 1 solenoid products adds to its versatility, allowing for easier maintenance and replacement processes. Additionally, the valve\u2019s construction minimizes internal parts binding thanks to Sun\u2019s floating style design which accommodates excessive installation torque and cavity/cartridge machining variations. This model also includes manual override capabilities with a detent mechanism designed for temporary actuation, supporting manual operation in emergency or specific system testing scenarios. The mechanical life expectancy of the manual control assembly stands at approximately 7,000 cycles, underlining its durability and reliability for industrial use. Overall, the DMDAMRN528 is equipped to provide efficient and stable performance in various hydraulic applications requiring robust control and high-pressure handling capabilities.

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.
