The Sun Hydraulics DMDAXNN914 (DMDAXNN914) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precision hydraulic systems. It features a direct-acting, balanced spool directional valve mechanism that operates without the need for minimum hydraulic pressure. This makes it highly effective in applications requiring reliable actuation regardless of system pressure fluctuations. The valve is engineered with a robust solenoid tube assembly that is fatigue rated for up to 5000 psi (350 bar), ensuring durability and long-term performance under high-pressure conditions. The closed transitions between spool positions B and R minimize performance loss while enhancing response times, particularly suitable for use as pilot controls where fast and consistent operations are critical. This model incorporates a wet armature design, meaning the coil's heat directly interacts with the hydraulic fluid, which can be crucial in applications where the valve remains energized over extended periods. Users should note that certain fluids may degrade under prolonged exposure to heat, affecting performance. The DMDAXNN914 also features interchangeable coils compatible with other Sun Series 1 solenoid products, adding versatility and ease of maintenance to its design. Additional durability is provided by Sun\u2019s floating style construction that prevents internal parts binding due to installation torque or machining variations. The manual override feature integrated into this model has a mechanical life expectancy of around 7,000 cycles, offering reliability even with manual actuations. Designed for systems using phosphate ester fluids, it utilizes EPDM seals to prevent damage from petroleum-based substances. With specifications including a flow capacity of up to 12 gpm (45 L/min) and maximum operating pressure of 5000 psi (350 bar), along with rapid response times typically around 50 ms, the DMDAXNN914 suits various high-demand hydraulic 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.
