The Sun Hydraulics DMDADNV814 (DMDADNV814) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed to operate efficiently with a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 12 gpm (45 L/min). Notably, the valve features a fatigue-rated solenoid tube assembly suitable for demanding applications. The DMDADNV814 is equipped with spools B and R that are closed during the transition between positions, optimizing performance by ensuring faster and more consistent response times, particularly useful in pilot control applications where capacity is less critical. The valve requires no minimum hydraulic pressure for operation, making it versatile for various hydraulic systems. This model also includes manual override options with a detent mechanism designed for temporary actuation. With a mechanical life expectancy of approximately 7,000 cycles and manual override features like a force requirement of 5 lbs at 1000 psi and stroke of .10 inches, it offers reliability in manual operations. The valve's wet armature design allows the working fluid to surround the armature which could be sensitive to prolonged energization periods especially with certain fluids like water-glycol mixtures. Additionally, the DMDADNV814 can be configured with EPDM seals suitable for phosphate ester fluids while being incompatible with petroleum-based substances which could damage the seals. Its construction incorporates Sun's floating style to minimize internal parts binding due to installation variances or machining inaccuracies. Interchangeable coils from other Sun Series 1 solenoid products add to its flexibility in system design. This model\u2019s robust build and adaptable configurations make it an excellent choice for dynamic hydraulic system applications requiring precise 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.
