The Sun Hydraulics DMDAXNV524 (DMDAXNV524) is a high-performance solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool directional control mechanism. Specifically designed for robust and precise fluid control, this model offers an impressive maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min). The valve's solenoid tube assembly is fatigue rated for high-pressure service, ensuring longevity and reliability in demanding applications. One of the standout features of the DMDAXNV524 is its closed transition between positions B and R, which enhances performance by providing faster and more consistent response times, especially suitable for pilot controls where capacity is less critical. The valve operates without requiring a minimum hydraulic pressure, adding to its versatility across various hydraulic systems. For manual override configurations, the DMDAXNV524 includes a detent mechanism designed for temporary actuation with a mechanical life expectancy of around 7,000 cycles. It also incorporates Sun's floating style construction which minimizes internal parts binding \u2014 a common issue in valves due to installation torque or machining variations. The valve's wet armature design allows the working fluid to surround the armature, helping manage heat during prolonged energization periods. However, this design necessitates careful selection of fluids as some can degrade under heat, affecting performance. Interchangeability with other Sun Series 1 solenoid products provides flexibility in system design and maintenance. With additional features like customizable seal options for different fluid types and easy coil replacement capabilities, the Sun Hydraulics DMDAXNV524 offers a reliable solution tailored for efficient directional control in hydraulic systems.

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.
